Rounding Decimals

Rounding is the process of adjusting the digits of a number to make it simpler and easier to work with, while keeping its value close to what it was.

Rounding to the nearest tenth means adjusting a number so that it has one digit after the decimal point.

When a number is exactly halfway between two values, it is typically rounded up to the higher value.

To round to the nearest whole number, if the decimal part is 0.5 or greater, round up; if it is less than 0.5, round down.

Look at the hundredths place (5). Since it is 5 or greater, round up the tenths place (5) to 6, resulting in 19.6.

The nearest dollar to $14.61 is $15.

Look at the hundredths place (4). Since it is less than 5, keep the tenths place (5) the same, resulting in 23.5.

To round to the nearest hundredth, look at the thousandths place. If it is 5 or greater, round up the hundredths place; if it is less than 5, keep the hundredths place the same.

Look at the decimal part (0.82). Since it is greater than 0.5, round up the whole number (1) to 2.

The nearest hundredth to 72.178 is 72.18.
