Answer:
39 2/3
Explanation:
First we will write 1 hour and 25 minutes as a mixed number. Since there are 60 minutes in an hour, this gives us
1 25/60
We can simplify this fraction, since both the numerator and denominator are divisible by 5:
1 (25÷5)/(60÷5) = 1 5/12
This is the fraction of hours he reads per nights. There are 7 nights in a week:
(1 5/12)(7) = 17/12(7/1) = 119/12
He reads for 4 weeks:
119/12(4/1) = 476/12
12 will go into 476 39 times, with 8 left over:
39 8/12
Both 8 and 12 are divisible by 4:
39 (8÷4)/(12÷4) = 39 2/3
