Worksheet Overview

QUESTION 1 of 10

If you are confident with multiplying fractions, dividing fractions should be a walk in the park!

There is just one more step to add to the process of multiplying fractions. 

 

A neat way to remember this process is with the acronym: KSF, which stands for Keep, Swap, Flip.

This little trick tells you precisely what to do to divide two fractions:

 

Keep the first fraction;

Swap the division sign to a multiply;

Flip the second fraction upside down.

 

Once you've done this, multiply your two fractions as usual and cancel your answer down if possible.

 

e.g. Complete the sum:

2
7
÷
1
3

 

If we apply KSF, we will reach the following sum: 

Keep Swap Flip
2
7
÷
1
3
2
7
x
3
1

 

We can now work out this new sum and it will give the same answer as the original one: 

2
7
x
3
1
=
6
7

 

Clever right?!

 

In this activity, you will practise dividing two fractions by applying the KSF (Keep, Swap, Flip) process and simplifying your answer if you can.
