Answer:
For every 5 blonde teachers there are 3 brown teachers.
Step-by-step explanation:
Here we have to find the ratio of blonde teachers to brown teachers
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
