Comparing and ordering numbers is useful when listing them by size. A good understanding of the value of a figure means you can compare one number with another and put several numbers in order. This KS3 Maths quiz will help you get the hang of ordering decimals.

Decimals are used for parts of numbers that are less than 1. When you put decimals in order, first compare the whole numbers, then the tenths, then the hundredths and then the thousandths. Unlike the numbers you are most used to, the value of numbers after decimal points goes down instead of up. That means that 0.099 is worth less than 0.1 - 1 tenth is more than 0 tenths, 9 hundredths and 9 thousandths.

Practise ordering decimals by playing this quiz. It may seem an easy task but take care! Read each question and look hard at the answers before you choose which one is right. Overconfidence can lead to careless mistakes!
