Rounding decimals worksheet with practice problems and a self-assessment section.

Problem Description:

The task involves rounding decimal numbers to the nearest hundredth. The worksheet provides two sets of numbers, and we need to round each number accordingly.

Key Concepts:

- Rounding to the nearest hundredth:
- Look at the digit in the thousandths place (the third digit after the decimal point).
- If this digit is 5 or greater, round up the hundredths place by 1.
- If this digit is less than 5, keep the hundredths place as it is.
- Drop all digits after the hundredths place.
