    39 2/3

    Step-by-step 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
