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….
