    a) the number is 52

    b) 27 is 45 percent of 60

    Step-by-step explanation:

    (a) 39 = 75% of x

    75/100 * x = 39

    x = 39 * 100 / 75

    = 39 * 4/3 = 13 * 4

    = 52

    b) 27 = x% of 60

    27 = (x/100) * 60

    x * 60 / 100 = 27

    x = 27 * 100 / 60

    = 27 * 5/3 = 9 * 5

    = 45
