Question

$$( - 12 ) : ( - 2 ) - ( + 15 ) : ( - 3 ) - ( - 20 ) : ( + 5 ) =$$

Evaluate

$15$

Solution Steps

Divide $-12$ by $-2$ to get $6$.

$$6-\frac{15}{-3}-\frac{-20}{5}$$

Divide $15$ by $-3$ to get $-5$.

$$6-\left(-5\right)-\frac{-20}{5}$$

The opposite of $-5$ is $5$.

$$6+5-\frac{-20}{5}$$

Add $6$ and $5$ to get $11$.

$$11-\frac{-20}{5}$$

Divide $-20$ by $5$ to get $-4$.

$$11-\left(-4\right)$$

The opposite of $-4$ is $4$.

$$11+4$$

Add $11$ and $4$ to get $15$.

$$15$$

Factor

$3\times 5$
