Solve -4(2+4)-4/2(-18-4(5))

$$\frac { - 4 ( 2 + 4 ) - 4 } { 2 ( - 18 - 4 ( 5 ) ) }$$

Evaluate

$$\frac{7}{19}\approx 0.368421053$$

Solution Steps

Add 2 and 4 to get 6.

$$\frac{-4\times 6-4}{2\left(-18-4\times 5\right)}$$

Multiply -4 and 6 to get -24.

$$\frac{-24-4}{2\left(-18-4\times 5\right)}$$

Subtract 4 from -24 to get -28.

$$\frac{-28}{2\left(-18-4\times 5\right)}$$

Multiply 4 and 5 to get 20.

$$\frac{-28}{2\left(-18-20\right)}$$

Subtract 20 from -18 to get -38.

$$\frac{-28}{2\left(-38\right)}$$

Multiply 2 and -38 to get -76.

$$\frac{-28}{-76}$$

Reduce the fraction \frac{-28}{-76} to lowest terms by extracting and canceling out -4.

$$\frac{7}{19}$$

Factor

$$\frac{7}{19} = 0.3684210526315789$$
