Item 1: To the tenths place. Round up to 0.9

Since we wish to round 0.88325 off to the tenths place, we need to look at the digit in the hundredths place. This digit is an 8. Since this digit is greater than 5, we round up, meaning we increase the number in the tenths place by one, from 8 to 9. This leaves us with 0.9.

Item 2: To the hundredths place. Round down to 0. 88

Since we wish to round 0.88325 off to the hundredths place, we need to look at the digit in the thousandths place. This digit is a 3. Since this digit is less than 5, we round down, meaning we drop off the end leaving only the tenths and hundredths place. This leaves us with 0.88.

Item 3: To the thousandths place. Round down to 0. 883

Since we wish to round 0.88325 off to the thousandths place, we need to look at the digit in the ten thousandths place. This digit is a 2. Since this digit is less that 5, we round down. This means we drop off the end leaving only the tenths, hundredths, and thousandths place. This leaves us with 0.883.
