The Singing Hedgehog Guide to:
Adding Fractions 2
Now we can try one with mixed numbers.
All we do is add the whole numbers separately then deal with the fractions.
Write the whole numbers on EVERY line - leave them out and you'll forget them.
Here is the sequence to follow:
Write out the question
Add the whole numbers
Put down the LCM
Do the "Not thinking very much at all" line
Work out what has happened to the bottoms
To turn 5 into 15 we times by 3
To turn 3 into 15 we times by 5
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 5 to make 5
write in the top values
add the tops
don't add the bottoms!
(It just tells us the size of slice)
