Question

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

• A. 1
• B. 1/5
• C. -1/5
• D. -1

Answer 1

The correct option is B

1/5

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

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

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

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