At SMS, 25% of the teachers teach math. If there are 50 math teachers, how many teachers are there all together at SMS?

200 teachers

Step-by-step explanation:

find the total number of teachers at SMS

25% are math teachers which = 50 math teachers

50 / 0.25 = 200

OR we can look at it as 25% is one quarter or 1/4.

what is 50 a quarter or 1/4 of?

50 x 4 = 200

200

Step-by-step explanation:

25 percent is known to be 1/4 of a number, so if 50 teachers represent 1/4 of all the teachers, that means that in order to get a full number, we must multiple 50 by 4 in order to get all 100% of the teachers.

By doing 50x4, we can conclude that 200 teachers teach at the school (aka 100% of all teachers)
