# Rounding large numbers

Large numbers can sometimes be awkward to work with and often we do not need to give exact values so we can sometimes round these numbers.

For example, if a woman wanted to know how many people lived in a city she might not need to know an exact answer: if the actual population was 1,172,246 (one million, one hundred seventy-two thousand, two hundred forty-six) then knowing the population was around 1,200,000 (one million, two hundred thousand) might be close enough.

## Reminder: Rules For Rounding Numbers

• If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 79 rounded to the nearest ten is 80
• If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 74 rounded to the nearest ten is 70
• All the numbers to the right of the place you are rounding to become zeros.

You can use the calculator below to enter numbers and have them rounded to the selected nearest place.
