Math- Percents

You know that to find an numerator or denominator of a fraction that would be equivalent to a percentage, you would have to put it to lowest terms. You would have to eventually apply the cross product rule. However, you don't have to go through all thought nonsense.  Just think of the problem as a regular proportional relationship. Put it to lowest terms so you can find a number that can be multiplied by the numerator and denominator. You will get your answers then.
