# The ratio of boys to girls in a school is 3:5, if there are 60 girls,how many boys are in the school?

There are $36$ boys in the school.

#### Explanation:

We can set up a proportion:

$\frac{3}{5} = \frac{x}{60}$

where $x$ is the number of boys in the school.

We cross-multiply:

$3 \left(60\right) = 5 x$

$180 = 5 x$

$x = 36$

There are $36$ boys in the school.
