Question

$\text{If}\frac{2}{5}+x=\frac{3}{5},\text{then}x=$ .

• A. $\frac{1}{5}$
• B. $\frac{2}{5}$
• C. $2$

Answer 1

The correct option is A $\frac{1}{5}$

$\text{Given:}\frac{2}{5}+x=\frac{3}{5}\text{On subtracting}\frac{2}{5}\text{from both the sides,}\text{we get,}\frac{2}{5}-\frac{2}{5}+x=\frac{3}{5}-\frac{2}{5}\Rightarrow x=\frac{3-2}{5}=\frac{1}{5}$
