Given the proportion a/b = 8/15, what ratio completes the equivalent proportion a/8 =?

The correct answer is,he equivalent proportion of a/8 is b/15.

Step-by-step explanation:

It is given that,

In both sides have fractions.

To find equivalent proportion of  

we have,

To find a/8 we have to cross multiply the above fractions.

a * 15 =8 * b

Therefore the equivalent proportion of a/8 is b/15

The correct answer is b/15.

The ratio that completes the equivalent proportion of a/8 = b/15

We are given the proportion that a/b = 8/15. The first thing to do is to cross multiply the given expression. Then, we can have:

15a = 8b

We are to find an equivalent proportion to a/8. So, from 15a = 8b, we are going to make (a) the subject of the equation and replace the value of (a) derived into a/8.

∴

a = 8b/15

Replacing the value of (a) into a/8, we have:

= 8b/15 ÷ 8

= 8b/15 × 1/8

= b/15

Therefore, we can conclude that the ratio that completes the equivalent proportion of a/8 = b/15
