    The answer to your question is: 7 7/8 km

    Step-by-step explanation:

    Data

    Lacy runs 5 1/4 km

    runs 1 1/2 times as far on Saturday

    Km run on Saturday = ?

    First calculate 1/2 of 5 1/4 convert 5 1/4 into an improped fraction

    5 1/4 = 21/4

    Now, divide by two (21/4) / 2 = 21 / 8

    She ran 5 1/4 + 21/8 Solve the sum

    = 21/4 + 21/8 = (42 + 21) / 8 = 63 / 8 = 7 7/8 km
