$$- \frac { 3 } { 10 } - \frac { 2 } { 15 }$$

$-\frac{13}{30}\approx -0.433333333$

Least common multiple of $10$ and $15$ is $30$. Convert $-\frac{3}{10}$ and $\frac{2}{15}$ to fractions with denominator $30$.

$$-\frac{9}{30}-\frac{4}{30}$$

Since $-\frac{9}{30}$ and $\frac{4}{30}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{-9-4}{30}$$

Subtract $4$ from $-9$ to get $-13$.

$$-\frac{13}{30}$$

$-\frac{13}{30} = -0.43333333333333335$
