To multiply fractions, simply multiply the top and bottom separately.

Example

4/5  x  1/3  = ?

4/5  x 1/3  = 4 x 1/5 x 3 – 4/15

 Steps Multiply the ‘top numbers’ of the fractions together à this gives you the ‘top number’ of your answer. Multiply the ‘bottom numbers’ of the fractions together à this gives you the ‘bottom number’ of your answer.‘top numbers’ = numerators‘bottom numbers’ = denominators

Dividing Fractions

To divide fractions, turn the 2nd fraction upside down and then multiply the

fractions as normal.

Example

5/6  ÷ 3/5 = ?

5/6 ÷ 3/5 = 5/6  x 5/3

x=  5/6  x 5/3 = 5  x 5/6  x 3 – 25/18
