The local YMCA has a ratio of 3:4 boys to girls at the beginning of summer break. At the end of summer break, the ratio was 5:2. If they YMCA began the summer with 105 total children, how many boys were enrolled at the end of summer break? What is the answer?

a. 3/4 ÷ 1/8 = 6

step-by-step explanation:

in the question, the number line represents 3/4 divided into 6 equal units. each arrow represents a unit and there are a total of six arrows.

the size of each unit is 1/8 as shown.

showing that 1/8 divides 3/4 into 6 divisions:

3/4 ÷ 1/8

= 3/4 x 8/1

= 3/1 x 8/4

= 3 x 2

= 6

hence, the number line represents six divisions given by 3/4 ÷ 1/8.
