In mathematics, rounding is a process that helps us approximate a number to the closest whole number, decimal or multiple of 10. To round a number to the nearest tenth, we have to look at the number after the decimal point. If the number after the decimal point is 5 or greater, then we round up the number and if it is less than 5, then we round down the number. For example, if a number is 3.7, then we round it up to 4 and if the number is 3.2, then we round it down to 3.
17 is a whole number, so to round it to the nearest tenth, we will look at the tenths place after the decimal point. Since the tenths place is 0, we will round down the number and the result will be 17.0. This means that 17 rounded to the nearest tenth is 17.0.
Understanding the Concept of Rounding
Rounding is a concept that is taught in elementary school, and it is important for children to understand the concept. When rounding numbers, the key is to look at the number after the decimal point and decide whether to round up or down. If the number after the decimal point is 5 or greater, then we round up the number and if it is less than 5, then we round down the number.
For example, if a number is 7.8, then we round it up to 8 and if the number is 7.2, then we round it down to 7. In addition, when you are rounding to the nearest tenth, you need to look at the tenths place after the decimal point. If the number is 0, then you will round down the number.
Examples of Rounding to the Nearest Tenth
Here are some examples of how to round numbers to the nearest tenth:
- 14.3 rounded to the nearest tenth is 14.3.
- 18.6 rounded to the nearest tenth is 18.6.
- 7.4 rounded to the nearest tenth is 7.4.
- 25.5 rounded to the nearest tenth is 25.5.
Conclusion
Rounding is a process that is used to approximate a number to the closest whole number, decimal or multiple of 10. To round a number to the nearest tenth, we have to look at the number after the decimal point. If the number after the decimal point is 5 or greater, then we round up the number and if it is less than 5, then we round down the number. 17 rounded to the nearest tenth is 17.0.
