In a school, 25 % of the teachers teach basic math. If there are 50 basic math teachers, how many teachers are there in the

school?

200 teachers

Step-by-step explanation:

Let t = teachers

t * 25% = basic math teachers

t *.25 = 50

Divide each side by. 25

.25t/.25 = 50/.25

t = 200

200

Step-by-step explanation:

The 50 basic math teachers are 25% of all the teachers of the school.

You can use a proportion.

50 is to 25% as x is to 100%

50/25 = x/100

10/5 = x/100

5x = 100 * 10

5x = 1000

x = 200

There are 200 teachers.
