Question

1. In a school, 5/9 of the children are boys and the number of girls is 100.Find the number of boys. please give me step-by-step solution please.​

Answer 1

So 5/9 are boys which means total parts we have are 9. if 5 parts are boys, then 4 are girls. ( 9-5= 4 )

4/9=100

if we divide 100 by 4, we can get the number of each part.

So 100 / 4 = 25

if each part is 25, that means 5 parts would be 125.

Hence, the number of boys is 125.
