Answer 1

`(3)/(5)`

Thinking behind the answer:

[] Let's say that the total class time is 5/5, or equal to one. This one represents the whole class period.

[] Now, if 2/5 of that class time are spent on test review, whatever chunk of class that's left is not spent on test review.

[] We can use subtraction to find our answer.

Explanation:

`(5)/(5)-(2)/(5)=(3)/(5)`
