    12.5 * 5 = ?

    Select all the pairs of ratios that form a proportion. Which are:
    1/6,4/20
    7/9,28/36
    14/18,21/27
    30/80,6/18.

    7/9,28/36
    14/18,21/27


    For which value of m is 4/16=m/24 a proportion

    Cross multiply and solve for m.
    16m = 96
    m = 96 / 16
    m = 6


    t/16=40/50

    Cross multiply and solve for t.
