Blonde : Brown

20: 12

10:6

5:3

For every 5 blonde teachers there are 3 brown teachers.

This can be further evaluated

Blonde : Brown

5:3

dividing both sides by 5

1: 3/5

For every 1 blonde teachers there are 3/5 brown teachers. It means that the brown teachers are 2/5 less than the blonde teachers.

1-2/5= 3/5

20* 3/5= 12
