Math Counters

Math CountersFifth grade math! If 15 counters are all, how many are 3 / 5 of the series?

Please i want to know the steps, I help my daughter doing her homework. Thank you !!!!!

You need to multiply 15 / 1 X 3X5

Multiply the numerators (15 and 3) to get 45.
Multiply the denominators (1 and 5) to obtain 5.

So now you have reduced the fraction 45 / 5

simplified. 5 goes into 45 nine times.

9 is your answer.

15 is 1, 3 is 5
15 / 1 x 3 / 5 then multiply
Cross to cancel 15 5 to make 3 / 1 x 3 / 1 for the answer is 9 / 1 or 9

I would use an LCD (lowest common denominator method) and set up ratios so that the problem was the same as finding equal fractions. So ...
1. 15 is everything.
2. All the other to compare contains 5 pieces.
3. 5 goes into 15 three times.
4. For individual pieces to "equality" in all five to all 15, you must multiply by 3 each.
5. So - 3 of 5 would be 3x3 5x3, or 9 out of 15.

Hope this helps ...

I'm in high school and I promise you need to know u nevr EHV

Well, I do not know the appropriate steps they teach students in 5th, but if there are 15 games, fifth of 15 (15% 5) is 3. which means 3 / 5 would be 9 (3x3 ).... So the answer is definitely 9 but I do not know what appropriate measures are sorry: (

X/15 = 3 / 5

you set up a porportion. x is the quantity of chips in a 15 which is 3 / 5 ... get?

15 * 3 / 5 = 9
Picture 15 as 5 groups. Each group has 3 counters. Multiply by 3 and the answer is .... 9!
