In this activity, we will practise rounding numbers to the nearest whole number and to 1, 2 and 3 decimal places.
Rounding numbers makes them easier to use, while keeping them close to the original number.
Whole Number
When we round to the nearest whole number, we look at the first decimal place. If it is 5 or above, we round up, if not we round down.
23.4966 rounds to 23 to the nearest whole number.
1 dp
When we round to 1 decimal place, we look at the second decimal place. If it is 5 or above, we round up.
23.4966 rounds to 23.5 to 1 dp.
2 dps
When we round to 2 decimal places, we look at the third decimal place. If it is 5 or above, we round up.
23.4966 rounds to 23.50 to 2 dps.
3 dps
When we round to 3 decimal places, we look at the fourth decimal place. If it is 5 or above, we round up.
23.4963 rounds to 23.496 to 3 dps.
All clear!
Let's try some questions now.
