Answer 1

There are 350 girls in the school.

Explanation:

1. Let's review all the information provided for answering the question correctly:

Ratio of number of boys to the girls = 5:7

Number of students in the school = 600

2. How many girls are there in the school?

Number of girls = x

Number of boys = 5/7x

x + 5x/7 = 600

7x + 5x = 4,200

12x = 4,200

x = 350

There are 350 girls in the school.

And the number of boys is (600 - 350) = 250.
