    Step-by-step explanation:

    Factory A proportion:

    3 : 2,000

    Factory B proportion:

    5 : 4,500 (this can be simplified):

    1 : 900

    Now plug in 18,000 to each proportion:

    Factory A:

    x : 18,000

    3 : 2,000

    x = 27

    Factory B:

    x : 18,000

    1 : 900

    x = 20

    Factory A had the greater amount of defects, 27
