Question

There are 2 boys for every 3 girls in Sappy Sunshine Childcare center. If there are a total of 171 girls at the center, how many boys are there? (do not include units in your answer, just the number)

Answer 1

114 boys

Explanation:

This question can be solved using a rule of three.

For each 2 boys, there are 3 girls on the center. So, how many boys will be there when there are 171 girls?

2 boys - 3 girls

x boys - 171 girls

`3x = 2*171`

Simplifying both sides by 3

`x = 2*57 = 114`

There are 114 boys there
