Explanation
Understanding fractions of a meter
Steps:
- One-thousandth means dividing 1 meter by 1000.
- Calculate 1 ÷ 1000 = 0.001.
- Match this value to the given choices.
- Identify option A as 0.001m.
Why A is correct:
- One-thousandth of a meter is defined as 1/1000 m, which equals 0.001 m by decimal conversion.
Why the others are wrong:
- B (0.01m) is one-hundredth of a meter (1/100 m).
- C (0.1m) is one-tenth of a meter (1/10 m).
- D (1m) is the full meter, not a fraction.
Final answer: A
