Solve: 2.001 × 100 - Decimal Multiplication Practice

$2.001\times100=$

To solve the problem $2.001 \times 100$, we need to apply the fundamental property of multiplying a decimal number by a power of ten.

• Step 1: Identify that $100 = 10^2$. This means we must move the decimal point in $2.001$ two places to the right.
• Step 2: Take the number $2.001$ and move the decimal point two places right:
  - Start: $2.001$
- After moving the first place: $20.01$ (Decimal point now between 0 and 0)
- After moving the second place: $200.1$ (Decimal point now after the digit 1).

Thus, the product of $2.001 \times 100$ is $200.1$.

Therefore, the final answer is $200.1$, which corresponds to choice 2.
