BACK TO WORKSHEETS
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:
|
÷ |
|
If we apply KSF, we will reach the following sum:
| Keep | Swap | Flip | ||||
|
÷ |
|
||||
|
x |
|
We can now work out this new sum and it will give the same answer as the original one:
|
x |
|
= |

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.
