Given that Althea volunteers in the school library for 2 1/4 hours on Mondays, Wednesdays, and Fridays.

She volunteers 2 1/4 hours a day.

3 × 9/4 = 27/4

Also, she volunteers for 1 3/4 hours on Tuesday and Thursday.

She volunteers 1 3/4 hours a day.

First we convert the improper fraction 1 3/4 to a proper fraction.
