Solve -3*4-1+1+2*4-2/4-1-2*4-2

$$\frac { - 3 \cdot 4 - 1 + 1 + 2 \cdot 4 - 2 } { 4 - 1 - 2 \cdot 4 - 2 }$$

Evaluate

$$\frac{6}{7}\approx 0.857142857$$

Solution Steps

Multiply -3 and 4 to get -12. Multiply 2 and 4 to get 8.

$$\frac{-12-1+1+8-2}{4-1-2\times 4-2}$$

Subtract 1 from -12 to get -13.

$$\frac{-13+1+8-2}{4-1-2\times 4-2}$$

Add -13 and 1 to get -12.

$$\frac{-12+8-2}{4-1-2\times 4-2}$$

Add -12 and 8 to get -4.

$$\frac{-4-2}{4-1-2\times 4-2}$$

Subtract 2 from -4 to get -6.

$$\frac{-6}{4-1-2\times 4-2}$$

Subtract 1 from 4 to get 3.

$$\frac{-6}{3-2\times 4-2}$$

Multiply 2 and 4 to get 8.

$$\frac{-6}{3-8-2}$$

Subtract 8 from 3 to get -5.

$$\frac{-6}{-5-2}$$

Subtract 2 from -5 to get -7.

$$\frac{-6}{-7}$$

Fraction \frac{-6}{-7} can be simplified to \frac{6}{7} by removing the negative sign from both the numerator and the denominator.

$$\frac{6}{7}$$

Factor

$$\frac{2 \cdot 3}{7} = 0.8571428571428571$$
