$$\frac{7}{8}-\frac{(-4)}{9}$$

$\frac{95}{72}\approx 1.319444444$

Fraction $\frac{-4}{9}$ can be rewritten as $-\frac{4}{9}$ by extracting the negative sign.

$$\frac{7}{8}-\left(-\frac{4}{9}\right)$$

The opposite of $-\frac{4}{9}$ is $\frac{4}{9}$.

$$\frac{7}{8}+\frac{4}{9}$$

Least common multiple of $8$ and $9$ is $72$. Convert $\frac{7}{8}$ and $\frac{4}{9}$ to fractions with denominator $72$.

$$\frac{63}{72}+\frac{32}{72}$$

Since $\frac{63}{72}$ and $\frac{32}{72}$ have the same denominator, add them by adding their numerators.

$$\frac{63+32}{72}$$

Add $63$ and $32$ to get $95$.

$$\frac{95}{72}$$

$\frac{5 \cdot 19}{2 ^ {3} \cdot 3 ^ {2}} = 1\frac{23}{72} = 1.3194444444444444$
