    Conversion: 1 1/2 = 1•2+1 = 3/2

    Divide: 3/2 by 1/4 = 3/2 • 4/1 = 12/2 = 6

    To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.

    Or change to %

    1 1/2 = 150% 1/4 = 25%

    150 divided by 25 = 6

    Number of runners needed = 1 1/2 / 1/4

    = 3/2 / 1/4

    = 3/2 * 4

    = 12/2 = 6 runners (answer).
