Rounding Decimals

Rounding is the process of adjusting 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 looking at the hundredths place (the second digit after the decimal) to decide whether to round the tenths place up or keep it the same.

Look at the third decimal place (8). Since 8 is 5 or more, round up the second decimal place (7) to 8. The answer is 72.18.

Look at the hundredths place (4). Since 4 is less than 5, keep the tenths place (5) the same. The answer is 23.5.

Look at the hundredths place (6). Since 6 is 5 or more, round up the tenths place (5) to 6. The answer is 5.6.

1.72 rounded to the nearest tenth is 1.7 because the hundredths place (2) is less than 5.

Look at the hundredths place (8). Since 8 is 5 or more, round up the tenths place (7) to 8. The answer is 56.8.

If the digit to the right of the place you are rounding to is 5 or more, round up. If it is less than 5, keep the digit the same.

Look at the decimal (0.41). Since it is less than 0.5, round down. The answer is 3.

Look at the third decimal place (1). Since 1 is less than 5, keep the second decimal place (3) the same. The answer is 10.23.
