Solve [-1/6+(-1/2)]

$$[ - \frac { 1 } { 6 } + ( - \frac { 1 } { 2 } ) ]$$

Evaluate

$$-\frac{2}{3}\approx -0.666666667$$

Solution Steps

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

$$-\frac{1}{6}-\frac{3}{6}$$

Since -\frac{1}{6} and \frac{3}{6} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-1-3}{6}$$

Subtract 3 from -1 to get -4.

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

Reduce the fraction \frac{-4}{6} to lowest terms by extracting and canceling out 2.

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

Factor

$$-\frac{2}{3} = -0.6666666666666666$$
