Rounding Decimals Worksheet Download - Free Printable

Problem Analysis:

The task involves rounding decimal numbers to specific place values (whole number, tenth, hundredth, etc.). The provided worksheet lists 20 problems, each requiring a different rounding precision. The answers are already filled in, and we need to verify their correctness based on the rules of rounding.

Rounding Rules Recap:

1. Rounding to the Nearest Whole Number:
- Look at the digit in the tenths place.
- If it is 5 or greater, round up.
- If it is less than 5, round down.

2. Rounding to the Nearest Tenth:
- Look at the digit in the hundredths place.
- If it is 5 or greater, round up.
- If it is less than 5, round down.

3. Rounding to the Nearest Hundredth:
- Look at the digit in the thousandths place.
- If it is 5 or greater, round up.
- If it is less than 5, round down.
