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

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

Evaluate

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

Solution Steps

Since \frac{1}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.

$$1-\left(\frac{1+1}{2}+\frac{1}{6}\right)$$

Add 1 and 1 to get 2.

$$1-\left(\frac{2}{2}+\frac{1}{6}\right)$$

Divide 2 by 2 to get 1.

$$1-\left(1+\frac{1}{6}\right)$$

Convert 1 to fraction \frac{6}{6}.

$$1-\left(\frac{6}{6}+\frac{1}{6}\right)$$

Since \frac{6}{6} and \frac{1}{6} have the same denominator, add them by adding their numerators.

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

Add 6 and 1 to get 7.

$$1-\frac{7}{6}$$

Convert 1 to fraction \frac{6}{6}.

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

Since \frac{6}{6} and \frac{7}{6} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 7 from 6 to get -1.

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

Factor

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