Subtracting Fractions 1

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

Here is the first example as a take away sum.

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

Take away the tops

Don't subtract the bottoms!
