Solve (-2/3)+(-1/-2)

$$( \frac { - 2 } { 3 } ) + ( \frac { - 1 } { - 2 } )$$

Evaluate

$$-\frac{1}{6}\approx -0.166666667$$

Solution Steps

Fraction \frac{-2}{3} can be rewritten as -\frac{2}{3} by extracting the negative sign.

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

Fraction \frac{-1}{-2} can be simplified to \frac{1}{2} by removing the negative sign from both the numerator and the denominator.

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

Least common multiple of 3 and 2 is 6. Convert -\frac{2}{3} and \frac{1}{2} to fractions with denominator 6.

$$-\frac{4}{6}+\frac{3}{6}$$

Since -\frac{4}{6} and \frac{3}{6} have the same denominator, add them by adding their numerators.

$$\frac{-4+3}{6}$$

Add -4 and 3 to get -1.

$$-\frac{1}{6}$$

Factor

$$-\frac{1}{6} = -0.16666666666666666$$
