Question

In a class of 54 students, the number of girls is two seventh of the boys. Find the number of girls

Answer 1

Step-by-step explanation:

There are 12 girls and 42 boys

If Girls = x and Boys is 54 - x,

x = 2/7 of 54 - x

x = (108 - 2x)/7

7x = 108 - 2x

9x = 108

x = 12

So, 54 - x = 54 - 12 = 42
