Subtracting Fractions 1
Subtracting is just the same as adding but we take away the tops.

Write out the question
Put down the LCM
Do the "Not thinking very much at all" line Work out what has happened to the bottoms
Do the same to the top as we did to the bottom Write in the top values

Don't subtract the bottoms!
