$$-1/3+1/7$$

$-\frac{4}{21}\approx -0.19047619$

Fraction $\frac{-1}{3}$ can be rewritten as $-\frac{1}{3}$ by extracting the negative sign.

$$-\frac{1}{3}+\frac{1}{7}$$

Least common multiple of $3$ and $7$ is $21$. Convert $-\frac{1}{3}$ and $\frac{1}{7}$ to fractions with denominator $21$.

$$-\frac{7}{21}+\frac{3}{21}$$

Since $-\frac{7}{21}$ and $\frac{3}{21}$ have the same denominator, add them by adding their numerators.

$$\frac{-7+3}{21}$$

Add $-7$ and $3$ to get $-4$.

$$-\frac{4}{21}$$

$-\frac{4}{21} = -0.19047619047619047$
