Can you please help me with this question thank you

Answer 1

Let x be the number of boys in the school the ratio of gilrs and boys in this school is:

`(120)/(x)`

but we know that in the school the ratio girls to boys is 3:2; which means that the ratios have to be equal:

`(120)/(x)=(3)/(2)`

Solving for x we have:

`\begin{gathered} (120)/(x)=(3)/(2) \\ x=(120)/((3)/(2)) \\ x=(120\cdot2)/(3) \\ x=(240)/(3) \\ x=80 \end{gathered}`

Therefore, there are 80 boys in the school.
