Answer 2

There are 9 boys in the class.

Step-by-step explanation:

Given:

The ratio of girls and boys= 3:8

The number of girls= 24

To find= the number of boys

Solution:

Let the number of girls and boys be 3x and 8x respectively

Now, we know there are 24 girls,

SO,

3x÷8x= 24÷ number of boys

3÷8= 24÷ number of boys

number of boys= 24×3÷8

Number of boys= 3×3

Number of boys= 9
