In this activity, we are going to look at missing values in ratio!

Let's look at basic ratio first!

This means there are 3 orange circles for every 4 green squares.

**If there were 6 orange circles, how many green squares would there be?**

Every time we have 3 circles we have 4 squares!

**To get 6:8 we multiplied both sides of the ratio by 2!**

Let's try a question without a diagram.

__Example__

Orange juice to lime juice is in the ratio 2:3.

If there are 14 orange juices, how many lime juices will there be?

**Answer**

** Orange juice : Lime juice**

How did we get to 14?

14 ÷ 2 = 7

So, we must **multiply both by 7!**

Therefore, we need** 21 lime juices!**

Let's try some questions!
