4. Hundredths: The digit in the hundredths place is 1. Since the digit to the right of it (2) is less than 5, we leave the digit in the hundredths place as it is. Therefore, the rounded value in the hundredths place remains 1.

5. Thousandths: The digit in the thousandths place is 2. Since the digit to the right of it (1) is less than 5, we leave the digit in the thousandths place as it is. Therefore, the rounded value in the thousandths place remains 2.

Therefore, when rounding off 9235.5612:

1.) Tens: 3

2.) Hundreds: 6
