$$\frac{3}{7}-\frac{(-5)}{12}$$

$\frac{71}{84}\approx 0.845238095$

Fraction $\frac{-5}{12}$ can be rewritten as $-\frac{5}{12}$ by extracting the negative sign.

$$\frac{3}{7}-\left(-\frac{5}{12}\right)$$

The opposite of $-\frac{5}{12}$ is $\frac{5}{12}$.

$$\frac{3}{7}+\frac{5}{12}$$

Least common multiple of $7$ and $12$ is $84$. Convert $\frac{3}{7}$ and $\frac{5}{12}$ to fractions with denominator $84$.

$$\frac{36}{84}+\frac{35}{84}$$

Since $\frac{36}{84}$ and $\frac{35}{84}$ have the same denominator, add them by adding their numerators.

$$\frac{36+35}{84}$$

Add $36$ and $35$ to get $71$.

$$\frac{71}{84}$$

$\frac{71}{2 ^ {2} \cdot 3 \cdot 7} = 0.8452380952380952$
