    Divide by the largest number that divides into both. (Greatest Common Factor)


    Example:


    28:56  > The GCF is 28 >  28/28 = 1 and 56 * 28 = 2. So the ratio is...............


    1:2


    15:25  > The GCF is 5  >  15 * 5 = 3 and 25 * 5 = 5. So the ratio is..................


    3:5
