The ratio of boys to girls in a classroom is 2:5

Add the two numbers:

2 + 5 = 7

Divide the gotten number by the total amount

70/7 = 10

Multiply each ratio number individually with gotten amount.

10 x 2 = 20

10 x 5 = 50

The ratio of boys to girls is 20:50, with 50 of them being girls.

50 is your answer

hope this helps
