The ratio of boys to girls in the park was 4 to 5 .if 270 children were in the park.How many girl?

150 are girls.

Step-by-step explanation:

There is an important difference between the way counts are viewed in ratio to that in fractions.

The ratio of boys : girls

4:5

so you have 4 boys and 5 girls making the whole count in its simplest form.

4+5=9

So to change the ratio proportion into fraction proportion we have:

Boys: 4/9

Girls: 5/9

It is given that the whole is 270 therefore the count of girls is:

5/9 x 270 = 150
