  • HELP ; MATH -

    Iam assuming you want to know if
    the ratios are true.

    Reduce each fraction to the lowest term
    and compare them by inspection:

    9. 4/12 = 3/9.
    Divide the numerator and denominator
    of the first fraction by 4.
    Divide the numerator and denominator
    of the 2nd fraction by 3.
    RESULTS: 1/3 = 1/3.

    10. 8/14 = 12/21, 4/7 = 4/7.

    11. 24/36 = 10/15 , 2/3 = 2/3.

    Try doing the others.
