Question

Find the value of x x-5/20=12/15

Answer 1

x =1 1/20

Explanation:

x-5/20=12/15

First simplify the fractions

5/20 = 1/4 and 12/15 = 4/5

x - 1/4 = 4/5

Add 1/4 to each side

x - 1/4+1/4 = 4/5+1/4

x = 4/5+1/4

The common denominator is 20

x = 4/5*4/4 + 1/4 *5/5

x = 16/20 + 5/20

x = 21/20

x = 20/20 + 1/20

x =1 1/20
