Rounding Decimals
Why Round Decimals?
Rounding decimals is necessary to simplify complex calculations and provide approximate answers.
Rules for Rounding Decimals:
-
Rounding to a specific place value: Identify the place value to which you want to round the decimal.
- Look at the digit to the right of the desired place value.
- If the digit is 0-4, round down (keep the digit in the desired place value the same).
- If the digit is 5-9, round up (increase the digit in the desired place value by 1).
-
Rounding to a specific number of decimal places: Identify the number of decimal places to which you want to round the decimal.
- Look at the digit to the right of the desired number of decimal places.
- If the digit is 0-4, round down (keep the digit in the desired number of decimal places the same).
- If the digit is 5-9, round up (increase the digit in the desired number of decimal places by 1).
Examples:
- Round 4.687 to the nearest tenth:
- Look at the digit to the right of the tenths place (7).
- Since 7 is greater than 5, round up to 4.7.
- Round 12.543 to two decimal places:
- Look at the digit to the right of the second decimal place (3).
- Since 3 is less than 5, round down to 12.54.
