$$\frac { 2 } { 5 } + \frac { 1 } { 4 }$$

$\frac{13}{20}=0.65$

Least common multiple of $5$ and $4$ is $20$. Convert $\frac{2}{5}$ and $\frac{1}{4}$ to fractions with denominator $20$.

$$\frac{8}{20}+\frac{5}{20}$$

Since $\frac{8}{20}$ and $\frac{5}{20}$ have the same denominator, add them by adding their numerators.

$$\frac{8+5}{20}$$

Add $8$ and $5$ to get $13$.

$$\frac{13}{20}$$

$\frac{13}{2 ^ {2} \cdot 5} = 0.65$
