Answer:
7:20
Explanation:
14+26=40
40 equals the total amount of teachers. Since we want to do the ratio of math teachers to the total of all teachers, we had to find 40.
You get 14:20 though if you want to simplify, find to common denominator (2) and dived both sides by it.
14/2 = 7
40/2 = 20
= 7:20
