Understand Ratios

In this activity, we will be looking at ratio.

Ratio is a relationship between  two amounts showing the number of times one value is contained within the other.   

Imagine that we had a jar of sweets and 1/4 of the sweets were white and 3/4 of the sweets were pink.

The fractions give us a proportion of the full jar, but we can write them as a ratio.

This is a proportion in terms of each other. 

Therefore, white is 1 part and pink is 3 parts.

We can write it as 1:3

White : Pink is 1:3            Pink : White is 3:1

Does that make sense?

Don't worry - we'll practise some questions together and you'll soon get the hang of them.
