Question

Find $x$, if $\frac{2}{5}+x=\frac{3}{5}$

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

Answer 1

The correct option is B

$\frac{1}{5}$

The given equation is $\frac{2}{5}+x=\frac{3}{5}$

Subtracting $\frac{2}{5}$ on both sides, we get

$\frac{2}{5}+x-\frac{2}{5}=\frac{3}{5}–\frac{2}{5}$

$\Rightarrow x=\frac{1}{5}$
