DIVISION ON FRACTIONS


Division on fractions is extremely easy. You just have to remember the rule to follow, and not get it confused with any other rule. You also have to remember to not do any "cross-canceling" until you have converted your division problem to multiplication as described below.


There is more than one method of dividing fractions. The easiest and most commonly taught way is to “invert and multiply.”To divide 2 fractions multiply the dividend by the reciprocal of the divisor.

Listed below is Dividing fractions examples:

(4/5) / (2/3) = (4/5) * (3/2)

(4/5) * (3/2) = (12/10)

12/10 = 1(1/5)

This is the quickest technique to divide fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one. Dividing anything by one leaves the value “anything” the same.
