Question

One fourth of the 120 students took wood shop. How many students did not take wood shop?

Answer 1

90 students.

Explanation:

Given 1/4 of the 120 students took woodshop, just take the 3/4 that didn't take it:

`(3)/(4)(120)`

Find common factors between 4 and 120 to simplify, so 4.

`(3)/(1) (30)`

Now multiple across to get 90.
