Question

$$\frac { - 8 } { 3 } + \frac { 7 } { 5 }$$

Evaluate

$-\frac{19}{15}\approx -1.266666667$

Solution Steps

Fraction $\frac{-8}{3}$ can be rewritten as $-\frac{8}{3}$ by extracting the negative sign.

$$-\frac{8}{3}+\frac{7}{5}$$

Least common multiple of $3$ and $5$ is $15$. Convert $-\frac{8}{3}$ and $\frac{7}{5}$ to fractions with denominator $15$.

$$-\frac{40}{15}+\frac{21}{15}$$

Since $-\frac{40}{15}$ and $\frac{21}{15}$ have the same denominator, add them by adding their numerators.

$$\frac{-40+21}{15}$$

Add $-40$ and $21$ to get $-19$.

$$-\frac{19}{15}$$

Factor

$-\frac{19}{15} = -1\frac{4}{15} = -1.2666666666666666$
