Solve 3*(1/2-1)

$$3 \times ( \frac { 1 } { 2 } - 1 )$$

Evaluate

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

Solution Steps

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

$$3\left(\frac{1}{2}-\frac{2}{2}\right)$$

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

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

Subtract 2 from 1 to get -1.

$$3\left(-\frac{1}{2}\right)$$

Express 3\left(-\frac{1}{2}\right) as a single fraction.

$$\frac{3\left(-1\right)}{2}$$

Multiply 3 and -1 to get -3.

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

Fraction \frac{-3}{2} can be rewritten as -\frac{3}{2} by extracting the negative sign.

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

Factor

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