How should the number 0.05060 be rounded to three significant figures?

Correct Answer: 0.0506

Step 1: Identify the significant figures in the number 0.05060. The significant figures are the non-zero digits and any zeros that are between them or after a decimal point. In this case, the significant figures are 5, 0, and 6.
Step 2: Count the first three significant figures. The first three significant figures are 5 (first), 0 (second), and 6 (third).
Step 3: Look at the digit immediately after the third significant figure to determine if rounding is needed. The digit after 6 is 0.
Step 4: Since the digit after 6 is 0 (which is less than 5), we do not round up. We keep the first three significant figures as they are.
Step 5: Write the rounded number, which is 0.0506.
