Solve -1/2-3-1

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

Evaluate

$$-\frac{9}{2}=-4.5$$

Solution Steps

Convert 3 to fraction \frac{6}{2}.

$$-\frac{1}{2}-\frac{6}{2}-1$$

Since -\frac{1}{2} and \frac{6}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-1-6}{2}-1$$

Subtract 6 from -1 to get -7.

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

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

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

Since -\frac{7}{2} and \frac{2}{2} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 2 from -7 to get -9.

$$-\frac{9}{2}$$

Factor

$$-\frac{9}{2} = -4\frac{1}{2} = -4.5$$
