    33 1/3 percent smaller

    Step-by-step explanation:

    The number a exceeds the number b by 50 percent.

    a = b + b*.5

    a = b (1.5)

    Divide by 1.5

    a/1.5 = b

    2/3a = b

    We want to find (a-b) / a to find the percent decrease

    (a-2/3a) / a * 100percent

    (1/3a) / a * 100 percent

    1/3 * 100 percent

    33 1/3 percent smaller
