Solve 3*(-1/2)-2

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

Evaluate

$$-\frac{7}{2}=-3.5$$

Solution Steps

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

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

Multiply 3 and -1 to get -3.

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

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

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

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

$$-\frac{3}{2}-\frac{4}{2}$$

Since -\frac{3}{2} and \frac{4}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-3-4}{2}$$

Subtract 4 from -3 to get -7.

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

Factor

$$-\frac{7}{2} = -3\frac{1}{2} = -3.5$$
