    16/100×y=72

    16y/100=72

    16y=7200

    y=7200/16=450

    Given

    16% of a number is 72

    To find

    The number

    Assumption

    Let the number be x.

    Answer and explanation

    Since 16% of x is 72

    In an equation it can be written as

     \frac{16}{100}  \times x = 72

    Thus

     \frac{16x}{100}  = 72

    So

    16x = 72 \times 100

    Thus x is

    x =  \frac{72 \times 100}{16}  = 450

    Thus x = 450

    Check

    Given that

    16% of x is 72

    That is

     \frac{16}{100}  \times x = 72

    Put x = 450 in LHS

    So

     \frac{16}{100}  \times 450 = 72

    Well the LHS simplifies to 72 and as LHS = RHS

    This means, x surely is equal to 450
