Solve -1/2+1-7

$$- \frac{ 1 }{ 2 } +1-7$$

Evaluate

$$-\frac{13}{2}=-6.5$$

Solution Steps

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

$$-\frac{1}{2}+\frac{2}{2}-7$$

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

$$\frac{-1+2}{2}-7$$

Add -1 and 2 to get 1.

$$\frac{1}{2}-7$$

Convert 7 to fraction \frac{14}{2}.

$$\frac{1}{2}-\frac{14}{2}$$

Since \frac{1}{2} and \frac{14}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{1-14}{2}$$

Subtract 14 from 1 to get -13.

$$-\frac{13}{2}$$

Factor

$$-\frac{13}{2} = -6\frac{1}{2} = -6.5$$
