Jen exercises 30 minutes each day on Monday, Wednesday, and Friday. She practices yoga for 45 minute on Tuesday. How many hours per week does Jen spend exercising and practicing yoga?

2 1/4 hours or 2.25 hours or 9/4 hours. This depends on your choices.

Step-by-step explanation:

Exercises

30 minutes = 1/2 hour

3 * 1/2 = 3/2 hours

Yoga

45 minutes = 45 minutes / 60 minutes//hour = 3/4 hour

Total

3/2 + 3/4 = 6/4 + 3/4 = 9/4

9/4 = 2 1/4 hours.
