What is the ratio of girls to boys in a class with 12 girls and 15 boys

The ratio should look like so:

girls : boys

There are 12 girls

There are 15 boys

Let's plug these numbers into the ratio:

12 : 15

Both 12 and 15 have the greatest common factor of 3. This means that it can be reduced by dividing 3 out of 12 and 15

(12 : 15) ÷ 3

4 : 5

Hope this helped!
