Question

1. The ratio of boys to girls is 4/5. If there
are 24 boys, how many girls are there?

Answer 1

Given:

The ratio of boys to girls is
`(4)/(5)`.

Number of boys = 24

To find:

The number of girls.

Solution:

We have,

Boys: Girls = 4:5

Let the number of boys be 4x and number of girls be 5x.

`4x=24`

`x=(24)/(4)`

`x=6`

Now,

Number of girls =
`5x`

=
`5(6)`

=
`30`

Therefore, the number of girls is 30.
