This is the answer

For this case we must know the number of hours per day.
 We have then:
 Monday = 1 3/4 hours
 Wednesday = 1 3/4 hours
 Friday = (1 3/4) / (2) hours
 Adding we have:
 1 3/4 + 1 3/4 + (1 3/4) / (2)
 Rewriting:
 1.75 + 1.75 + 1.75 / 2
 1.75 (1 + 1 + 1/2)
 1.75 (2 + 1/2)
 1.75 * (5/2)
 4.375
 = 4 + 0.375
 = 4 + 375/1000
 = 4 + 15/40
 = 4 + 3/8
 = 4 3/8
