Adding Fractions 1
Adding and subtracting fractions is like dealing with smelly babies:
Sort out their bottoms!
Here is the sequence to follow:
Write out the question
Put down the LCM
Do the "Not thinking very much at all" line
Just write two fractions over the LCM
Work out what has happened to the bottoms
To turn 4 into 12 we times by 3
To turn 6 into 12 we times by 2
Now we just do the same to the top
as we did to the bottom
times 3 by 3 to make 9
times 1 by 2 to make 2
write in the top values
add the tops
don't add the bottoms!
(It just tells us the size of slice)
