How Do You Round Numbers?

To round numbers, decide on the place to which to round. Round up if the digit itself or the digit to its right is five or greater, and round down if the number is less than five. Rounding a number means to reduce its digits while keeping the value similar.

In two-digit numbers, rounding to the tens place requires rounding based on the tens digit. In three-digit numbers, rounding to the tens place requires rounding based on the number to the right of the tens digit. For example, rounding 93 to the nearest tens amount makes it 90, whereas rounding 113 to the nearest tens amount makes it 110.
