Rounding to the Nearest Tenth
Rounding numbers to the nearest tenth is a fundamental mathematical operation used to simplify calculations and improve data accuracy. It involves adjusting a number to the nearest multiple of 0.1.
Rounding Rules
- If the digit in the hundredth place (one digit to the right of the decimal point) is 5 or greater, round up the number.
- If the digit in the hundredth place is less than 5, round down the number.
Rounding ‘1.988’, Round 1.988 to the nearest tenth
To round ‘1.988’ to the nearest tenth, we apply the rounding rules:
- The digit in the hundredth place is 8, which is greater than 5.
- Therefore, we round up the number.
The rounded value of ‘1.988’ to the nearest tenth is 1.9.
Applications of Rounding
Rounding to the nearest tenth has various applications in real life, including:
- Simplifying calculations in measurements, such as rounding a length of 2.47 meters to 2.5 meters.
- Improving data accuracy in financial calculations, such as rounding a stock price of $123.456 to $123.50.
- Making data more manageable and easier to interpret, such as rounding the average temperature of a month to the nearest tenth of a degree.
Helpful Answers: Round 1.988 To The Nearest Tenth
What is the rule for rounding to the nearest tenth?
When rounding to the nearest tenth, if the hundredth place digit is 5 or greater, round up the tenth place digit by one. If the hundredth place digit is less than 5, leave the tenth place digit unchanged.
Why is rounding important?
Rounding simplifies calculations, improves data accuracy, and enhances readability by removing unnecessary detail. It allows us to focus on the most significant digits and make informed decisions based on the rounded values.
Can rounding introduce errors?
Yes, rounding can introduce errors, especially when dealing with large datasets or when multiple rounding operations are performed consecutively. However, the magnitude of the error is typically small and can be minimized by using appropriate rounding techniques.
