Question

Find: $0.1\times 51.7$

Answer 1

Find the required value:

The decimal $0.1$ can be expressed in fractions as $\frac{1}{10}$.

The decimal $51.7$ can be expressed in fractions as $\frac{517}{10}$

$\therefore 0.1\times 51.7=\frac{1}{10}\times \frac{517}{10}$

$=\frac{517}{100}$

$=5.17$

Hence, $\mathbf{0}\mathbf{.}\mathbf{1}\mathbf{\times }\mathbf{51}\mathbf{.}\mathbf{7}$ is $\mathbf{5}\mathbf{.}\mathbf{17}$.
