Solve -4/2--1/2

$$\frac { - 4 } { 2 } - \frac { - 1 } { 2 }$$

Evaluate

$$-\frac{3}{2}=-1.5$$

Solution Steps

Divide -4 by 2 to get -2.

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

Fraction \frac{-1}{2} can be rewritten as -\frac{1}{2} by extracting the negative sign.

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

The opposite of -\frac{1}{2} is \frac{1}{2}.

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

Convert -2 to fraction -\frac{4}{2}.

$$-\frac{4}{2}+\frac{1}{2}$$

Since -\frac{4}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.

$$\frac{-4+1}{2}$$

Add -4 and 1 to get -3.

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

Factor

$$-\frac{3}{2} = -1\frac{1}{2} = -1.5$$
