    Answer:

    Old number = 150

    Step-by-step explanation:

    Given information;

    Percentage decreased = 22%

    New number obtain = 117

    Find:

    Old number

    Computation:

    Old number = New number obtain[100 / (100 – 22)]

    Old number = 117[100 / (100 – 22)]

    Old number = 117[100 / (78)]

    Old number = 11,700 / 78

    Old number = 150

    100-22=78

    117=78%

    117/78=1.5

    1.5=1%

    1.5 x 100=150
