1. 0.001*1000= ?

  • A. 0.1
  • B. 0.1
  • C. 0.1
  • D. 0.1

Answer: Option B

Explanation:

To multiply a decimal by 1000, you move the decimal point three places to the right. 
Here's the calculation:
  1. Start with the number 0.001.
  2. Move the decimal point 3 places to the right (since 1000 has three zeros).
  3. The decimal point starts before the first zero: 0.001
  4. Move it one place to the right: 00.01
  5. Move it a second place to the right: 001.0
  6. Move it a third place to the right: 001.0
  7. The zeros in front of the 1 can be dropped, leaving the number 1. 

Therefore, 0.001 * 1000 = 1. The correct option is 2.
