Question

Find $0.5\times 0.05$.

Answer 1

Find $\mathbf{0}\mathbf{.}\mathbf{5}\mathbf{\times }\mathbf{0}\mathbf{.}\mathbf{05}$:

$$\begin{gathered} 0.5\times 0.05 \\ =\frac{5}{10}\times \frac{5}{100} \\ =\frac{25}{1000} \\ =0.025 \end{gathered}$$

Therefore, $\mathbf{0}\mathbf{.}\mathbf{5}\mathbf{\times }\mathbf{0}\mathbf{.}\mathbf{05}\mathbf{=}\mathbf{0}\mathbf{.}\mathbf{025}$
