Answer 2

Your answer is here

Boys and Girls ratio is 5:7

And number of boys is 700

It means boys ratio equal to the boys numbers

Then 5 ratio = 700

If 5 ratio =700 then

1 ratio = 700 ÷ 5

1 ratio = 140

If 1 ratio =140 then

7 ratio = 140 × 7

7 ratio = 980

It means the number of girl is 980

Answere is 980
