Answer:

16

Step-by-step explanation:

Let the number be X

3/4 of X = 15

Multiplying out gives;

3X = 4x15

3X= 60

X = 20

Therefore, 4/5 of 20

Putting X = 20 we have;

4/5 x 20 = 16.

16-3/4= 15.25

Answer:

20

Step-by-step explanation:

Represent the box with x, to make it easier.

3/4 of x is 15.

Whenever we see "of", we have to think multiplication!

3/4 * x = 15

Multiply both sides by 4/3 to cancel out the 3/4 on the left side and solve for x.

x = 15 * 4/3

15 * 4/3 = 60/3 = 20

x = 20
