ChatGPT said:
To round the number 43.586 to the nearest tenth, hundredth, and one, we follow the rules of rounding based on the place value we’re focusing on.
1. To the nearest tenth:
- The tenths place is the first digit after the decimal point, which is 5 in this case.
- Look at the digit in the hundredths place, which is 8.
- Since 8 is greater than or equal to 5, we round the tenths place up by one.
So, rounding 43.586 to the nearest tenth gives us 43.6.
2. To the nearest hundredth:
- The hundredths place is the second digit after the decimal point, which is 8.
- Look at the digit in the thousandths place, which is 6.
- Since 6 is greater than or equal to 5, we round the hundredths place up by one.
So, rounding 43.586 to the nearest hundredth gives us 43.59.
3. To the nearest one:
- The ones place is the first digit to the left of the decimal point, which is 3.
- Look at the digit in the tenths place, which is 5.
- Since 5 is greater than or equal to 5, we round the ones place up by one.
So, rounding 43.586 to the nearest one gives us 44.
Explanation:
Rounding is a simple method of reducing the number of digits in a number while maintaining its value as close as possible to the original number. Each rounding rule focuses on a specific place value (tenths, hundredths, ones), and the next digit to the right of the place value determines whether we round up or leave the digit unchanged. If the digit is 5 or greater, we round up; if it is less than 5, we keep the original digit.
In this case:
- Nearest tenth: Rounded the decimal to one place after the decimal point.
- Nearest hundredth: Rounded the decimal to two places after the decimal point.
- Nearest one: Rounded the whole number to the nearest integer.
These steps help simplify numbers while keeping them as accurate as possible for practical uses, such as measurements or calculations.
