Solve 18:(-3)-32:8/(-56:7+5*4):(-3)=

$$\frac { 18 : ( - 3 ) - 32 : 8 } { ( - 56 : 7 + 5 \cdot 4 ) : ( - 3 ) } =$$

Evaluate

$$\frac{5}{2}=2.5$$

Solution Steps

Divide 18 by -3 to get -6.

$$\frac{-6-\frac{32}{8}}{\frac{\frac{-56}{7}+5\times 4}{-3}}$$

Divide 32 by 8 to get 4.

$$\frac{-6-4}{\frac{\frac{-56}{7}+5\times 4}{-3}}$$

Subtract 4 from -6 to get -10.

$$\frac{-10}{\frac{\frac{-56}{7}+5\times 4}{-3}}$$

Divide -56 by 7 to get -8.

$$\frac{-10}{\frac{-8+5\times 4}{-3}}$$

Multiply 5 and 4 to get 20.

$$\frac{-10}{\frac{-8+20}{-3}}$$

Add -8 and 20 to get 12.

$$\frac{-10}{\frac{12}{-3}}$$

Divide 12 by -3 to get -4.

$$\frac{-10}{-4}$$

Reduce the fraction \frac{-10}{-4} to lowest terms by extracting and canceling out -2.

$$\frac{5}{2}$$

Factor

$$\frac{5}{2} = 2\frac{1}{2} = 2.5$$
