Solution Steps

Fraction \frac{1}{-27} can be rewritten as -\frac{1}{27} by extracting the negative sign.

$$2\left(-\frac{1}{27}\right)+\frac{1}{-27}$$

Express 2\left(-\frac{1}{27}\right) as a single fraction.

$$\frac{2\left(-1\right)}{27}+\frac{1}{-27}$$

Multiply 2 and -1 to get -2.

$$\frac{-2}{27}+\frac{1}{-27}$$

Fraction \frac{-2}{27} can be rewritten as -\frac{2}{27} by extracting the negative sign.

$$-\frac{2}{27}+\frac{1}{-27}$$

Fraction \frac{1}{-27} can be rewritten as -\frac{1}{27} by extracting the negative sign.

$$-\frac{2}{27}-\frac{1}{27}$$

Since -\frac{2}{27} and \frac{1}{27} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-2-1}{27}$$

Subtract 1 from -2 to get -3.

$$\frac{-3}{27}$$

Reduce the fraction \frac{-3}{27} to lowest terms by extracting and canceling out 3.

$$-\frac{1}{9}$$

Factor
