Rounding money
A sum often gives more decimal places than money has. Round to the nearest penny, pound, ten or hundred, and know when to do it.
Task 1To the nearest penny4 questions
Money has two decimal places. A sum can give three or more, so the answer has to be rounded.
- Step 1: look at the third decimal place
- Step 2: if it is 5 or more, the second decimal place goes up by one
- Step 3: if it is 4 or less, the second decimal place stays as it is
- Step 4: drop everything after the second decimal place
Worked example: £3.476 has a third decimal place of 6, so it rounds up to £3.48. £3.472 has a third decimal place of 2, so it stays at £3.47.
