#### Worksheet Overview

In this activity, we will use our knowledge of fractions and multiples to solve a range of problems.

Let's work through one together.

I ate ¼ of a delicious apple pie and saved  to eat later.

I gave the rest of the pie to some friends who dropped in.

What fraction was served to my friends?

1st step: Convert

Convert ¼ to eighths so that both fractions have the same denominator and then will be easier to work with.

4 x 2 = 8 so we need to multiply both the nominator and the denominator by 2 to change ¼ into eighths.

So I ate  and I saved          A total of ⅜

2nd step: Subtract

The total pie was originally a whole =

So ⅝  of the apple pie was served to my friends.

Let's move on to the questions now.
