Reginald read his novel three nights in a row. Each night, he read for

3/4 of an hour.

How many hours did Reginald read his novel altogether?

9 hours

2 1/2 hours

2 1/4 hours

4 hours

2 1/4 hours

Step-by-step explanation:

Each night, he read for 3/4 hours = 3*60/4 = 45 minutes.

He read for 3 days.

So in total, he read for:

3*45 = 135 minutes.

135 minutes is 2 hours and 15 minutes. 15 minutes is 1/4 of an hour.

So the correct answer is:

2 1/4 hours
