Let's look at how to compare and order decimals, using number lines to help us. Look at this next example. 6.82 (six and eighty-two hundredths) is less than 6.86 (six and eighty-six hundredths).
A decimal is a way of writing a number that is not whole. Decimal numbers are 'in between' numbers. For example, 10.4 is in between the numbers 10 and 11. It is more than 10, but less than 11.
