Question

0.2 × 100 = a 0.2 b 2 c 20 d 200

Explanation:

Step1: Recall decimal multiplication rule

When multiplying a decimal by 100, we move the decimal point two places to the right.
For \(0.2\times100\), moving the decimal point in \(0.2\) two places right gives \(20\).
Or calculate directly: \(0.2\times100 = \frac{2}{10}\times100 = 2\times10 = 20\).

Answer:

C. 20
