    Pierre ran 19 and 13/20 miles.

    Given:

    marathon length : 26 2/10 miles

    pierre's length ran : 3/4 of the way.

    Multiply the fractions.

    Convert the marathon length from a mixed fraction into a fraction.

    26 2/10 = ((26*10) + 2) / 10 = (260+2) / 10 = 262/10

    262/10 * 3/4 = (262*3) / (10*4) = 786/40 = 19 26/40

    19 26/40 simplified to 19 13/20 miles

    26 : 2 = 13

    40 : 2 = 20
