Unitary proportion sounds scary, but its quite simple. The word UNI means one (think of unicycle - one wheel) and proportion is about the relationship between objects.

So Unitary proportion is all about finding the value of 1 item and then using this.

**Example: 5 pens cost 55 p, what is the cost of 8 pens?**

5 pens = 55 pence

1 pen = 11 pence (Just divide by 5)

8 pens = 88 pence (Multiply by 8)
