Question

Find $\frac{4}{5}$ of $20$.

Answer 1

Find the required value:

The required values can be calculated as,

$\frac{4}{5}\mathrm{of}20=\frac{4}{5}\times 20$ $\left[\because a\mathrm{of}b=a\times b\right]$

$\Rightarrow \frac{4}{5}\mathrm{of}20=\frac{4}{1}\times 4$

$\Rightarrow \frac{4}{5}\mathrm{of}20=4\times 4$

$\Rightarrow \frac{4}{5}\mathrm{of}20=16$

Hence, $\frac{\mathbf{4}}{\mathbf{5}}$ of $\mathbf{20}$ is $\mathbf{16}$.
