The Correct Answer and Explanation is:
Correct Answer: 17.3
Explanation
Rounding a number to the nearest tenth means adjusting it to one digit after the decimal point. In this case, the number is 17.3, and we want to round it to the nearest tenth.
The number 17.3 already has one digit after the decimal point, which is the number 3 in the tenths place. To determine whether to round this digit up or keep it the same, we need to look at the digit immediately to the right of the tenths place—this would be the hundredths place. However, in the number 17.3, there is no digit in the hundredths place, which means it’s effectively a 0.
Here’s a step-by-step breakdown:
- Identify the tenths place: In 17.3, the digit 3 is in the tenths place.
- Look at the digit to the right (hundredths place): There is no digit, which means it is assumed to be 0.
- Apply rounding rules:
- If the hundredths digit is 5 or greater, we round the tenths digit up by 1.
- If it is less than 5, we keep the tenths digit as is.
Since the digit to the right is 0, which is less than 5, we do not round the tenths place up. Therefore, 17.3 stays the same when rounded to the nearest tenth.
This rounding method ensures consistency in numerical reporting, especially when dealing with measurements, currency, or data that require precision. Rounding helps simplify values while maintaining reasonable accuracy. In this case, because the number already ends in the tenths place and does not need adjustment, the final rounded result remains:
