Question

Mark the correct alternative in each of the following:

0.002 × 0.5 =

(a) 0.0001 (b) 0.001 (c) 0.01 (d) 1

Answer 1

$$\begin{gathered} 0.002\times 0.5 \\ =\frac{2}{1000}\times \frac{5}{10} \\ =\frac{2\times 5}{1000\times 10} \\ =\frac{10}{10000} \\ =\frac{1}{1000} \\ =0.001 \end{gathered}$$

Hence, the correct answer is option (b).
