Verified by Experts
The correct answer is:
A
Step 1: Identify significant figures in the numbers involved.
The number 97.52 has 4 significant figures, and the number 2.54 has 3 significant figures.
Step 2: Perform the division:
\( \frac{97.52}{2.54} = 38.3937 \)
Step 3: Apply the rule of significant figures in division, which states that the result should have the same number of significant figures as the measurement with the least number of significant figures.
In this case, 2.54 has the least significant figures (3), so we round 38.3937 to 3 significant figures.
Step 4: Rounding 38.3937 to 3 significant figures gives us 38.4.
Therefore, the correct answer is A.
