How to Round Decimals
Rounding decimals is a way to simplify a number by making it shorter while keeping its value close to the original.
Rounding Decimals Lesson
- Identify the rounding place value. This is the digit you want to round to (e.g., the tenths place, the hundredths place).
- Look at the digit immediately to the right. This is the “deciding digit."
- Apply the rounding rule:
If the deciding digit is 4 or less (0, 1, 2, 3, 4), you keep the rounding digit the same.
If the deciding digit is 5 or greater (5, 6, 7, 8, 9), you add one to the rounding digit (rounding up). - Drop all digits to the right of the rounding place.
Examples
Example 1: Rounding to the nearest tenth
Let’s round 7.362 to the nearest tenth.
- The rounding place is the tenths place. The digit is 3.
- The digit to its right is 6.
- Since 6 is greater than 5, we add one to the 3, which becomes 4.
- We drop the digits 6 and 2.
The rounded number is 7.4.
Example 2: Rounding to the nearest hundredth
Let’s round 12.8419 to the nearest hundredth.
- The rounding place is the hundredths place. The digit is 4.
- The digit to its right is 1.
- Since 1 is less than 5, we keep the 4 the same.
- We drop the digits 1 and 9.
The rounded number is 12.84.
