Thursday 26 May - Ms Steans Group - Finding a common denominator


How to Find a Common Denominator


Challenge time for some of you!

We know that to add or subtract fractions, the fractions MUST have a common denominator.

Watch this video clip which will show you a couple of strategies for finding a common denominator.




Challenge:

Solve the following problems in your maths book ... please show your working out so I can see how you have made the equivalent fractions.

1. 2/5 + 3/10 =
2. 1/3 + 2/9 =
3. 1/6 + 7/24 =

Super challenge ... put your thinking caps on!

4. 2/3 + 1/5 =
5. 4/3 + 1/4 =

Good luck!  Come and see me if you get stuck!
