Rounding Numbers: Round 2.74 To The Nearest Tenth.
Rounding numbers is a technique used to approximate a number to a specified level of precision. It involves replacing a number with a nearby number that is easier to work with or more appropriate for a given context. Rounding to the nearest tenth means approximating a number to the nearest multiple of 0.1.
Steps for Rounding to the Nearest Tenth
To round a number to the nearest tenth, follow these steps:
- Identify the digit in the tenth place (the first digit after the decimal point).
- If the digit in the hundredth place (the second digit after the decimal point) is 5 or greater, round up the digit in the tenth place by 1.
- If the digit in the hundredth place is less than 5, leave the digit in the tenth place unchanged.
Identifying the Digit to Round, Round 2.74 to the nearest tenth.
The digit to round is the digit in the tenth place. For example, in the number 2.47, the digit to round is 7.
Rounding Up or Down
To round a number up, the digit in the tenth place is increased by 1. To round a number down, the digit in the tenth place is left unchanged.
For example, 2.47 is rounded up to 2.5, while 2.43 is rounded down to 2.4.
