Write One Number as a Fraction of Another

In this activity, we will be changing quantities into fractions, following a few simple rules.

What is 5 minutes as a fraction of one hour?

First, we need to make the units the same. 

We need to work out how many minutes there are in 1 hour.

There are 60 minutes in one hour.

As a fraction, we would write this as: 5/60

Let's try another. 

Write 12 metres as a fraction of 1 km.

Again, first, we need to make sure the units are the same.

There are 1,000 m in 1 km.

As a fraction, we would write this as:  12/1,000

How do you feel about all that? Confident?!

Let's try some questions.
