Divide a decimal by 100 — place value check Compute 9.724 ÷ 100.

Difficulty: Easy

Correct Answer: 0.09724

Explanation:


Introduction / Context:
Dividing by 100 moves the decimal point two places to the left. This question reinforces place value and guards against common shifts in the wrong direction.



Given Data / Assumptions:

  • Find 9.724 ÷ 100 exactly.
  • No rounding; exact decimal required.


Concept / Approach:
Dividing by 10, 100, 1000 shifts the decimal point left by 1, 2, 3 places respectively.



Step-by-Step Solution:
9.724 ÷ 100 ⇒ shift the decimal two places left: 0.09724.



Verification / Alternative check:
Compute 9.724 × 0.01 = 0.09724; same result because 1/100 = 0.01.



Why Other Options Are Wrong:
972.4 and 9.724 correspond to multiplying by 100 or doing nothing; 0.9724 shifts one place only; “None of these” is incorrect since the exact value is listed.



Common Pitfalls:
Moving the decimal to the right; forgetting that division by 100 reduces the magnitude.



Final Answer:
0.09724
