Question

Given this proportion, what ratio completes the equivilent proportion a/8?


`(a)/(b)= (8)/(15)`
Please show your work so that I know how to do this.

Answer 1

To solve this problem you must follow the steps below:

You have a/b=8/15, Then:

1. You must divide in both side of the given proportion by 8:

a/bx8=8/15x8

2. When you simplify, you obtain:

a/8b=1/15

3. Now, you must multiply both sides by "b", as below:

axb/8b=1xb/15

4. Finally, when you simplify, you have:

a/8=b/15
