18

Step-by-step explanation:

We can use a proportion to find out the number of teachers that are needed.

3/70 = x/14,700

70x = 3 * 14,700

70x = 44,100

x = 630

630 teachers are needed altogether. Since there are already 612 teachers, the number of more teachers who are needed is the difference between 630 and 612.

630 - 612 = 18

Answer: 18
