4. The first thing you must do is make the bottom numbers the same
5. To make them the same you need to think of the lowest number that they will both divide into and the quickest way to do this may be to multiply the two bottom numbers together
13. now we need to add the top numbers together and leave the bottom numbers alone =
14. now we need to add the top numbers together and leave the bottom numbers alone = =
15. We have ended up with a “top heavy” fraction. Divide the bottom number into the top to get a final answer of =
16. We have ended up with a “top heavy” fraction. Divide the bottom number into the top to get a final answer of =
17. Subtracting fractions You use exactly the same method as for adding but at the end you subtract the top numbers from each other rather than add them
