what is 71.6 rounded to the nearest tenth?
The correct answer and explanation is:
To round 71.6 to the nearest tenth, you need to focus on the number in the tenths place, which is the first digit to the right of the decimal point. In this case, the number is 6.
When rounding to the nearest tenth, you look at the number in the hundredths place, which is the second digit after the decimal point. If this number is 5 or greater, you round the tenths place up by one. If it is less than 5, you leave the tenths place unchanged.
For 71.6:
- The tenths place is 6.
- The hundredths place is absent, but it can be considered as 0.
- Since the hundredths place is less than 5, you leave the tenths place as 6.
Thus, 71.6 rounded to the nearest tenth is 71.6.
Explanation:
Rounding numbers is a way to simplify a value, making it easier to work with while maintaining an approximate accuracy. In this case, rounding to the nearest tenth means adjusting the number to one decimal place, based on the value of the second decimal (the hundredths place).
The rules for rounding are as follows:
- Look at the digit in the place value to which you’re rounding (in this case, the tenths place).
- Check the digit in the next place value (the hundredths place).
- If the digit is 5 or more, increase the rounding digit by 1. If it’s less than 5, leave the rounding digit unchanged.
In our example, since the hundredths place is 0, the tenths digit stays the same. This results in 71.6 as the rounded value.
