$$\frac { 1 } { 21 } + \frac { ( - 7 ) } { 22 }$$

$-\frac{125}{462}\approx -0.270562771$

Fraction $\frac{-7}{22}$ can be rewritten as $-\frac{7}{22}$ by extracting the negative sign.

$$\frac{1}{21}-\frac{7}{22}$$

Least common multiple of $21$ and $22$ is $462$. Convert $\frac{1}{21}$ and $\frac{7}{22}$ to fractions with denominator $462$.

$$\frac{22}{462}-\frac{147}{462}$$

Since $\frac{22}{462}$ and $\frac{147}{462}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{22-147}{462}$$

Subtract $147$ from $22$ to get $-125$.

$$-\frac{125}{462}$$

$-\frac{125}{462} = -0.27056277056277056$
