There is a 6th grade math homework problem I need help with, regarding percentage bars. Can somebody help me?
The problem is worded terribly, unless the class already has an established vocabulary for this kind of problem. It doesn't really even say that the percent bar pictured is the one Marjorie used. That aside, it appears to me that you are correct: 15 and 44% are the answers to questions 2 and 3, respectively.The reason you should discard the 0.34 and 1% option is because the percent bar is explicitly described as having the 1% mark, so even if Marjorie had done no work, that mark would still be there.There are no other marks, and Marjorie is described as just looking at one train (dimples), so the 15/44% is the only possibility.This interpretation of this somewhat ambiguous question is, to me, makes the most sense with regards to the concepts that the authors are attempting to convey.
PLZ HELP ME WITH MY 8th GRADE MATH PROBLEM!! I'm not asking for the answer just help me PLZ!!!?
A. Free throw percentage is calculated by diving the number of free throws made by the number free throws attempted. If you look at the box score, you will these stats FTA (free throws attempted) FTM (free throws made) FTP (free throw percentage) So your basic formula is: FTP = FTM / FTA Or if you awnt to put this into a nice percentage format, you can multiply it by 100 FTP = (FTM / FTA) * 100 B. In the beggining of the game, Tony Wade had (FTM / FTA) * 100 = 82 After his first foul, his stat changed to: (FTM + 1 / FTA + 2) * 100 = 78 C. Since the number of free throws made is never more than the number of free throws attempted, we are always dealing with number between 0 to 100 D. The first equation (FTM / FTA) * 100 = 82 Solve for FTM FTM / FTA = 82/100 FTM / FTA = 0.82 FTM = 0.82 * FTA The second equation (FTM + 1 / FTA + 2) * 100 = 78 Plug in FTM from above, and solve for FTA (0.82 * FTA + 1 / FTA + 2) * 100 = 78 (0.82 * FTA + 1 / FTA + 2) = 78 / 100 (0.82 * FTA + 1 / FTA + 2) = 0.78 (0.82 * FTA + 1) = 0.78 (FTA + 2) 0.82 * FTA + 1 = 0.78 * FTA + 1.56 0.82 * FTA - 0.78 * FTA = 1.56 - 1 0.04 * FTA = 0.56 FTA = 0.56 / 0.04 FTA = 14 So he had 14 free throw attempts before the game E. FTM = 0.82 * FTA FTM = 0.82 * 14 FTM = 11.48 Obviously he couldn't make 0.48 free throw. This is what we call rounding error. Unfortunately the numbers you have given don't work out right. I have double and triple checked my answer and they are correct. (11.48 / 14) * 100 = 82 (12.48 / 16) * 100 = 78 No other number can cause that kind of rounding error. If he had made 11 of 14, then his percentage would have been 18 or 19 percent, and 12 of 14 wouls have give the percentage of 85 or 86 percent. But the process that I explained is correct. I hope this helped Kia

I need help on this 6th grade math homework problem regarding percent bars and basketball players. Can somebody help me?
On B, there are 10 bars, so the marked bars are at 1/10, 2/10, 3/10, ... , 9/10So the question is, what is 1/10 of 371, and what is 1/10 of 725? When you divide by 10, you can just move the decimal place once to the left. 1/10 of 371 is 37.1, and 1/10 of 725 is 72.5.So the bars for Yao ming should just be you counting by 37.1:0, 37.1, 74,2, 111.3, 148.4, 185.5, 222.6, 259.7, 296.8, 333.9, 371He hit 301 free throws, so that's just past 296.8 (the 80% bar). You color all those boxes, plus a little further. So we estimate Mao makes about 81% of free throws (give or take.)On the bars for Shaquille O' Neil you should count by 72.5:0, 72.5, 145, 217.5, 290, 362.5, 435, 507.5, 580, 652.5, 725451 is beyond the 435 mark (60%) so I'd call it 63%. Shaq made about 63% of his free throws.Compare these to the %s you got in part A.On C, I'm not 100% sure I know what it's asking, but here's what I'm assuming. You need to remember that Will used 4 bars, and Alisha used 10 bars. Either the benchmarks they are asking about are fractions or percents.Will is using 25% or 1/4 benchmarks.Alisha is using 10% of 1/10 benchmarks.On D, it looks like you have a little freedom, so I can really only tell you what I'd do personally.15 is divisible by 5, so I'd use benchmarks of 1/5 or 20% for Angela (20% is 1/5 of 100.) This comes out to 3.0, 3, 6, 9, 12, 15This means Angela hits 4/5 or 80% of her free throws.20 is divisible by 5 as well. (20% comes out to 4.)0, 4, 8, 12, 16, 2015 is under 16, so Emily makes slightly less than 80% of her free throws. (Not important, but it's actually 3/4.)16 is divisible by 4, so I'd try 25% first. 25% of 16 is 4.0, 4, 8, 12, 1613 is over 12 so they shoot over 75%. Unfortunately so does Angela, so we need a better answer. Let's try dividing by 5 like Angela. 16/5 is 3.2.0, 3.2, 6.4, 9.6, 12.8, 1613 is over 12.8, so Cristina makes over 80% of her free throws.Cristina is the best free throw shooter, because she is the only one who makes over 80% of her free throws.I think the idea of this problem is to let the student experiment with using the method. If you could guide him/her without actually telling him/her how to divide it up, that would be ideal.On E (D #2), you just need to know that percents represent part of a whole, and so do fractions. Ratios can do that too, though that isn't always what they're doing. 4/5, 80%, and 4:5 are all ways of expressing the idea that 4 out of every 5 will have a certain outcome.Best of luck.

7th grade math problem please help im desperate?
For your first fraction, you have 7/17.5 Then point when you want to reduce that is to end up with a fraction with whole numbers on the top and the bottom of the fraction bar. So if you divide both top and bottom by 0.5 first, you get: 7/0.5 14 ------------ = ----------- 17.5/0.5 35 And since both 14 and 35 is divisible by 7, you can divide each of those numbers by 7, and now you get: 14/7 2 -------- = ------ 35/7 5 And so apparently, yes, you can reduce 7/17.5 to get 2/5. And yes, that is correct. As for 2 7 ---- = ---- 5 x ...you should just cross multiply, meaning you take the numerator of one fraction and multiply it by the denominator of the other fraction. That amount will be equal to the answer found when you take the denominator of the first fraction and multiply it by the numerator of the other fraction. Anyway, you probably know that. If you do it here you get: 2 * x = 5 * 7 And that is 2 * x = 35. Which means that twice of x is equivalent to 35. Which means that if you divide 35 by two, you should get x. 2x=35. x=35/2 x=17.5 ...which is your answer.
