Which of the following is equivalent to $\frac{2}{5}$?

• A. $4\%$
• B. $2.5$
• C. $0.25$
• D. $2\times \frac{1}{5}$

Answer 1

The correct option is D

$2\times \frac{1}{5}$

Determine the equation which is equivalent to $\frac{2}{5}$.

As we all know, every number multiplied by one equals the number itself.

Therefore,

$\begin{array}{rcl}\frac{2}{5}& =& \frac{2}{5}\times 1\\ & \Rightarrow & =\frac{2\times 1}{5}\\ & \Rightarrow & =2\times \frac{1}{5}=0.4=0.4\times 100\%=40\%\end{array}$

Hence, the correct choice is “Option D”.
