Question

$$\frac { - 9 } { 10 } + \frac { 22 } { 15 }$$

Evaluate

$\frac{17}{30}\approx 0.566666667$

Solution Steps

Fraction $\frac{-9}{10}$ can be rewritten as $-\frac{9}{10}$ by extracting the negative sign.

$$-\frac{9}{10}+\frac{22}{15}$$

Least common multiple of $10$ and $15$ is $30$. Convert $-\frac{9}{10}$ and $\frac{22}{15}$ to fractions with denominator $30$.

$$-\frac{27}{30}+\frac{44}{30}$$

Since $-\frac{27}{30}$ and $\frac{44}{30}$ have the same denominator, add them by adding their numerators.

$$\frac{-27+44}{30}$$

Add $-27$ and $44$ to get $17$.

$$\frac{17}{30}$$

Factor

$\frac{17}{2 \cdot 3 \cdot 5} = 0.5666666666666667$
