# Rounding Whole Numbers

## Hundreds Place

Rounding a number means to change its value slightly so it is not as exact as the original number. Numbers are rounded to a certain place value - tens, hundreds, thousands. etc..

Numbers are rounded to make it easier to do various math processes such as estimating costs in one's head or dividing larger numbers.

RULE: To round a three digit number or higher number to the nearest hundreds place:

• If the number in the tens place of a three digit number is less than five, round the number down to the nearest hundreds place. If the number in the tens place is greater than five, round it up to the nearest hundreds place.

Example 1: Round 236 to the nearest hundreds place

• The number 3 in the tens place is less than five. Therefore the number 236 is rounded down to 200.
• 236 rounded to the nearest hundreds place is 200.

Example 2: Round 274 to the nearest hundreds place.

• The number 7 in the tens place is greater than five. Therefore the number 274 is rounded up to 300.
• 274 rounded to the nearest hundreds place is 300.

Example 3: Round 934 to the nearest hundreds place.

• The number 3 in tens place is less than five. Therefore the number 934 is rounded down to 900.
