decimal is a way of writing a number that is not whole.

We place digits to the left or right of the decimal point depending on their value. On the left we have the tens and ones and on the right we have the tenths and hundredths.

Let's have a look at the number 41.32.

Lets look at how money can be rounded. 


Rounding money or decimals

Rounding a price to the nearest pound is the same as rounding a decimal to the closest whole number.

Look at the digit in the tenths place. That’s the digit after the decimal point:

  • if it is 5 or more, then round it up
  • if it is less than 5, then round down

So if the amount of pennies after the decimal point is more than 50p we round up, if it is less than 50p we round down.

For example, £2.80 rounded to the nearest whole number is £3, because the digit in the tenths position is 8.
