The sections on Mixtures and Work simply add one or two steps from your previous knowledge from Chapters 3 and 4. Answer the following questions to help you address your issues with these types of problems.
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?

1) If you know what to put in the chart, then it makes mixture problems much easier because it's easier to see what you need to multiply by. For me, it's difficult cause it's... confusing >__< You won't ALWAYS need an extra third row. It's optional, but it's helpful. ^^
ReplyDelete2) Like I said, if you know what to put in, then the work problems will be easier. For me, it's easier, but sometimes I get confused of what to put in the chart. You have to remember that the work rate will ALWAYS be a fraction. And if they completed ALL their work, then the solution will be 1. There must be a variable [obviously], and... that's it. :D
3) I absolutely LOATHE mixture problems. To me, not only is it confusing, but it's very hard to set it up in a chart because I don't know what would equal what, and what times 'x' blah blah, and it just doesn't "click" into my head. Work problems are pretty... well... not HARD, but not EASY.

1. Mixture problems were easy to set up in a chart because we just need to fill in the information from question into a chart. You sometimes need extra 3rd row.
ReplyDelete2. Work problems were harder than mixture problems, but still easy because, same as mixture problems, we just need to fill the information on question on chart. You always need to remember that rate is always fraction.
3. Using decimal is more difficult because we can cancel out fractions, but to make decimal into whole number, we need to times multiple of 10.

1. Mixture problems were pretty easy to set up in a chart because, well... you just needed to interpret the information from the problem and put it in a chart! You will not always need an extra third row in your chart, although many problems will still require you to have one.
ReplyDelete2. Work problems were actually easier to set up in a chart than setting up a chart for mixture problems because... I don't know... they were just easier for me to set up! Maybe it's because the information for the chart is already in the problem? No, wait, mixture problems are the same in that. Hmm... Well, you should always know that the rate is always a fraction, and that you should know for sure if you're supposed to find the time or the rate.
3. Using decimals in mixture problems was harder for me because you can always cross out fractions, but you can't with decimals. You also have to multiply decimals by 10, 100, or 1000 to end up with whole numbers, and if you do that, the numbers that were whole numbers to begin with can end up getting pretty big.

ReplyDelete1) Honestly, it isn't really that hard but its really annoying when you have to do 20 of them... But it makes solving the problem easier and sometimes you may need a 3rd row sometimes but you dont NEEEEED it.
ReplyDelete2) Its not hard to set it up, but sometimes i just can't find what to put in the spaces of the 'unknown' box, You gotta remember that Rate= always fraction.
3) I honestly dont care, tho id rather do work problems because i like fractions better than decimals :))
1) No mixture problems are not difficult, because all I have to do is plug in numbers.
ReplyDelete2) Work problems are kind of difficult to set up in a chat because I sometimes get confused where to put something, and sometimes forget to do 1/x. (making it into fractions)
3) They both are okay, because we can change both of them differently.

1) Mixture problems aren't difficult to set up in a chart. If you are able to understand the information the chart helps you organize the information and create the equation to solve the problem. I think I would need a 3rd row because that's the mixture that we're trying to make and we can know its value if we have a 3rd row.
2) Since I am used to using charts for the word problems, the charts are no longer difficult. They are only difficult when I set the chart wrong. In a chart I have to remember the type of chart. The chart could be an interest chart or it could be a chart for rate/time/distance.
3) I think they are equally difficult (hehe) because they have both pros and cons. In the mixture problems, we have to divide the decimal which sometimes messes up my multiplications. Also, in a word problem we have to multiply the LCD to get rid of the denominator.
1) I think using a chart with mixture problems is helpful and easier than not using a chart at all because it helps you collect in all the information at once. I think you need an extra 3rd row in a mixture problem.
ReplyDelete2) Setting work problems in a chart is the most difficult to me because it's confusing to put what in which column. You have to remember converting your time and fractions for these problems.
3) For me, using fractions for work problems is the most difficult because I struggle with fractions.
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
ReplyDeleteMixture problems are not difficult to set up in a chart because putting info in the chart makes it easier to solve the question. I won't always need an extra 3rd row in my chart.
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
Work problems aren't difficult to set up in a chart because they don't have much info to confuse me. I have to remember that the whole work equals 1 and the work rate should always be in fractional form.
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
Decimals are harder for me to solve because I get confused with the decimal points.

ReplyDeleteMixture problems were not difficult to set up for me in a chart because i just had to know what type of equation suit the problem and just plug in the right information. It helped me solve all the questions a lot easier than just doing it and i wont always need a third row in my chart but sometime i do.
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
work problems are not THAT difficult but i think i will make mistakes in the test. Because if i say "it's SOOOOO eashaeee (easy)" and then get bad grades in the test and i'll get embarrassed so anyways i sometimes forget to times all the same number on each side and that the work rate should always be in fractional form.
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
Fractions are harder for me to solve i dont really know why because if i know why then i can get all 100 in my tests but i think its because fractions get in my way. more than decimals which all you really need to do is just times the 100 and 1000 and 10000 and so on....
Decimals are harder for me to solve because I get confused with the decimal points.
1. The mixture problems are not that hard to set up a chart. Some problems might be, but most of the case, it is fairly easy. You just need to put in the information and make a equation based on it. Also, we do not need a third line for the chart. It depends on the problem.
ReplyDelete2. For me, the problems that requires me to set up charts are fairly easy. Because if i find the components of the chart, all I have to do left is to plug them in my equation and solve. However, for me, solving a problem without a chart is more easier. I think its because I learnt not using a chart first. You always need to remember that the rate is a fraction on work rate problems.
3. I find Decimals more hard to solve. Fractions are way easy to me to solve. I can't explain it well why, but the thing is that I do not like to calculate long stuff on my paper. Since long decimals in a problem mostly requires to multiply or divide that with another number, it makes me a bit tired doing all that math and calculations. On the other hand, fractions are easy to solve because I can cut down the values of the fractions which makes the math easier.
1. Mixture problems were not hard, probably because I had to use charts. Making charts is actually easier then setting up a confusing and bunch of equations. Chart had shorten my time because chart had organized my time to set up the equation.
ReplyDelete2. I think word problems are more easier to solve when you use chart because it simply organizes what is on the problem. Actually now I can't solve any word problems with out charts. You need to remember to put right information in the right box.
3. I think using decimal is more ANNOYING because when you are dividing decimal makes number so large that it takes much time for me to solve them.
1)They aren't difficult to set up as long as you know when to times the right speed. You do always need a 3rd row for mixture problems so that you can create an equation, not an expression.
ReplyDelete2) Work problems aren't hard to set up as well in a chart because it's just plugging in numbers, but you have to remember things about hours and minutes, and you have to make sure you are multiplying the rate by the right number (for example, 3 or 1/3) because the problem doesn't always tell you what to do straightforwardly.
3) Decimals are harder because you need to do multiplication and they are generally more complex than work fractions, but with fractions, you have to be careful not to multiply by the wrong number or simplify wrong.
1) Mixture problems were not very difficult since we already learned how to solve problems by setting up charts. And for me, organizing information in neat little charts is better than scribbling down in bunch of messy equations. It's easier to read I guess. You don't always need the third row.
ReplyDelete2) In my opinion, setting up word problems in charts are easier than just solving them directly. Like I said it's more organized. And I kind of like reading the stories in word problems. The only thing that you have to be careful is to put the right information in correct boxes.
3) For me, dealing with fractions are easier because you just have to simplify them instead of dividing everything up into bits.
I don't think that mixture problems are difficult to set up since it is very easy once I know what to put in each box.
ReplyDeleteI think it is easy to set up charts for word problems because all I have to do is put in the information given in the chart. I have to remember that the work rate needs to be in a fraction for a work problem.
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
I think fractions more difficult for me to solve. I think this because when adding fractions, we have to have the least common denominator.
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
ReplyDeleteMixture problems are sometime difficult to set up, if the question has lots of information that can confuse you very easily. I think rather than solving it, knowing what to put where is more difficult. We will not always need the extra 3rd row in our chart, because it could be easier to solve the problem without it.
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
Work problems are not as hard to set up in charts than the mixture problems, because the information given are usually easier to understand and pick up. It is always important to remember to read the directions carefully and make sure the info you are putting in the chart are necessary and in the right places.
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
For me, it is more difficult to solve with decimals because it takes longer time for me to find out the answers/info, and sometimes using decimals will confuse me in other areas of the problem. Fractions seem simple for me to solve, because they do not confuse me as much.
I hope this gets uploaded this time!
