In this worksheet, students multiply simple pairs of proper fractions, writing the answer in its simplest form. Key stage:  KS 2

Curriculum topic:  Number: Fractions, Decimals and Percentages

Curriculum subtopic:  Multiply Proper Fractions

Difficulty level:   ### QUESTION 1 of 10

Multiplying fractions is not the same as adding them.

We do NOT try to get them to have the same denominators.

Multiply the top numbers together.

Multiply the bottom numbers together.

 1 × 2 9 3

1 × 2 = 2

9 × 3 = 27

 2 27

Example

Work out the following, remembering to give your answer in its lowest terms.

 3 × 4 5 8

3 × 4 = 12

5 × 8 = 40

This gives:

 12 40

But this must be reduced by dividing top and bottom by 4.

 3 10

which we write as   3/10.
