Solve {l}{1}{1/2}{-1}

$$\left. \begin{array} { l } { 1 } \\ { \frac { 1 } { 2 } } \\ { - 1 } \end{array} \right.$$

Evaluate

$$-\frac{1}{2}=-0.5$$

Solution Steps

Convert 1 to fraction \frac{2}{2}.

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

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

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

Subtract 1 from 2 to get 1.

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

Convert 1 to fraction \frac{2}{2}.

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

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

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

Subtract 2 from 1 to get -1.

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

Factor

$$-\frac{1}{2} = -0.5$$
