Remember that there are 100 p in a pound.
So if we subtract 1 p from £1 we get 99 p or £0.99
Subtract 253 p from £10.
Working in pounds, we must work out £10.00 - £2.53
Remember there are decimals when we subtract with money and we need to consider the place values of pounds and pence.
The answer must be written with a £ sign, so the answer is £7.47
