Answer 2

Hello!

Part A

To get the ratio of girls to boys you do

amount of girls: amount of boys

The answer is 260: 240

First you have to find the total amount of students

240 + 260 = 500

To get the ratio of boys to the total amount of students you do 

amount of boys: amount of students

The answer is 240:500

Hope this helps!
