Question

A group of 10 Science Club students is on a field trip. That number of students represents 20% of the total number of students in the Science Club. What is the total number of students in the Science Club?

Choices:

A 20

B 30

C 50

D 80

Answer 1

Explanation:

So 20% of the science club students is 10.

I am trying to find 100% as this equals ALL the students on the science club trip.

20% = 10

100% / 20% = 5

This means I need to multiply both sides by 5 to get to 100%
20% = 10

(Multiply both sides by 5)

100% = 50

Therefore there are 50 students in the science club (C)
