## What is the ratio of 18:10?

To work out the ratio you firstly look at the two numbers in the ratio and check to see **which times table they are both in. ** 18 and 10 are both in the 2 times table. So then we can simplify this ratio by dividing both numbers by 2. **So the answer is 9:5.** Another way calculating equivalent ratios is to **multiply both numbers in the ratio by the same number**. For example, if we multiply both numbers by 2 then we would get 36:20. If we multiplied them both by 3 we would get 54:30 and so on and so on….. So to summarise some of the ratios that are equivalent to 18:10 are 9:5, 36:20, 54:30….
