Rounding Off Decimals Worksheet #9 featuring 24 decimal numbers with underlined digits for rounding practice.

Let's solve the rounding problem step by step. The task is to round each decimal to the place value of the underlined digit.

We'll go through each number, identify the underlined digit and its place value, then apply rounding rules:

> Rounding Rule:
> - If the digit to the right of the underlined digit is 5 or greater, round up.
> - If it's less than 5, round down (keep the underlined digit the same).
