What is three quarters of 28? How do you do the sum?

3/8*28

Cancel 4 and 28

3*7

Multiply 3 by 7 to get 21.

21

3/4 of 28 is 21

There are four parts to a quarter so you divide 28 by 4:

28/4=7

and then because you want to know three quarters you just times 7 by 3:

7x3=21

therefore three quarters of 28 is 21
