Question

Ratio of number of boys to girl is 5 to 4 there are 60 girls in choir how many boys are there

Answer 1

Since the ratio of boys to girls is 5:4 and there are 60 girls, let b be the number of boys and g be the number of girls. Then:

`\begin{gathered} (b)/(g)=(5)/(4) \\ \Rightarrow(b)/(60)=(5)/(4) \\ \Rightarrow b=(5)/(4)*60 \\ \Rightarrow B=75 \end{gathered}`

Therefore, there are 75 boys in the choir.
