$$\frac{2}{5}+(\frac{-3}{4})$$

$-\frac{7}{20}=-0.35$

Fraction $\frac{-3}{4}$ can be rewritten as $-\frac{3}{4}$ by extracting the negative sign.

$$\frac{2}{5}-\frac{3}{4}$$

Least common multiple of $5$ and $4$ is $20$. Convert $\frac{2}{5}$ and $\frac{3}{4}$ to fractions with denominator $20$.

$$\frac{8}{20}-\frac{15}{20}$$

Since $\frac{8}{20}$ and $\frac{15}{20}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{8-15}{20}$$

Subtract $15$ from $8$ to get $-7$.

$$-\frac{7}{20}$$

$-\frac{7}{20} = -0.35$
