In this worksheet, students write one number as a fraction of another. Key stage:  KS 3

Curriculum topic:   Ratio, Proportion and Rates of Change

Curriculum subtopic:   Express One Quantity as a Fraction of Another

Difficulty level:   ### QUESTION 1 of 10

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

What are 5 minutes as a fraction of one hour? First, you 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 1000 m in 1 km.

As a fraction, we would write this as:
 12 1000

Write:

36 m as a fraction of 1 km =
 A B

Write:

963 m as a fraction of 1 km =
 A B

Write:

95 m as a fraction of 1 km =
 A B

Write:

73 p as a fraction of £1 =
 A B
