Question

The ratio of girls to boys in a swimming club was 2:3 There were 14 girls. How many boys were there in the club?

Answer 1

number of girls = 14

number of boys = ?

total number = x

ratio of girls to boys = 2:3

Therefore,

`\begin{gathered} \text{ numbers of girls=}(2)/(5)* x \\ 14=(2)/(5)x \\ 2x=70 \\ x=(70)/(2) \\ x=35 \end{gathered}`

Number of boys = total number - number of girls

Number of boys = 35 - 14 = 21
