A simple way is to work out 1/5 first. To work out 1/5 of something you divide it by 5. So 10 divided by 5 is 2. So this means 1/5 is 2. However we want 2/5 not 1/5. To get 2/5 we just double 1/5. 1/5*2 is 4. This means 2/5 is the same as 4. Your answer is 4.
This is an example of multiplication of fractions. 2/5 of 10 means (2/5)*10. It can also be written as (2/5)*(10/1)In order to multiply fractions, just multiply the numerators which are 2 and 10 and the product is 20. And multiply also the denominators which are 5 and 1 and the product is 5. The result would be written as 20/5. The final answer should be written in simplified form which is 4. Solution: (2/5)*10 = (2/5)*(10/1) = 20/5 = 4
