DIVIDING FRACTIONS

Division of fractions involves using the reciprocal (flipped form) of the second fraction. The reciprocal of a number is such that the product of a number and its reciprocal is 1. To get the reciprocal, simply interchange (flip) the numerator and the denominator. one third becomes three ones, four fifths becomes five fourths, and so on.

After the second fraction has been flipped, the division problem turns into a multiplication problem, and the numerators and denominators are multiplied straight across.
