Answer:when rounding 0.0089: - To 1 decimal point, it is 0.0. - To 2 decimal points, it is 0.01. - To 3 decimal points, it is 0.009
Explanation:
1. Rounding to 1 decimal point: - Look at the digit immediately to the right of the desired decimal point, which is the tenths place. - If this digit is 5 or greater, round up the preceding digit. - If this digit is 4 or less, leave the preceding digit as it is. - In this case, the digit in the tenths place is 0, which is less than 5. Therefore, the number 0.0089 rounded to 1 decimal point remains as 0.0. 2. Rounding to 2 decimal points: - Look at the digit immediately to the right of the desired decimal point, which is the hundredths place. - If this digit is 5 or greater, round up the preceding digit. - If this digit is 4 or less, leave the preceding digit as it is. - In this case, the digit in the hundredths place is 8, which is greater than 5. Therefore, the number 0.0089 rounded to 2 decimal points becomes 0.01. 3. Rounding to 3 decimal points: - Look at the digit immediately to the right of the desired decimal point, which is the thousandths place. - If this digit is 5 or greater, round up the preceding digit. - If this digit is 4 or less, leave the preceding digit as it is. - In this case, the digit in the thousandths place is 9, which is greater than 5. Therefore, the number 0.0089 rounded to 3 decimal points becomes 0.009.
