Solve 1/2(-1/2)-1/4

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

Evaluate

$$-\frac{1}{2}=-0.5$$

Solution Steps

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

$$\frac{1}{2}\left(-\frac{1}{2}\right)-\frac{1}{4}$$

Multiply \frac{1}{2} times -\frac{1}{2} by multiplying numerator times numerator and denominator times denominator.

$$\frac{1\left(-1\right)}{2\times 2}-\frac{1}{4}$$

Do the multiplications in the fraction \frac{1\left(-1\right)}{2\times 2}.

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

Fraction \frac{-1}{4} can be rewritten as -\frac{1}{4} by extracting the negative sign.

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

Since -\frac{1}{4} and \frac{1}{4} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 1 from -1 to get -2.

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

Reduce the fraction \frac{-2}{4} to lowest terms by extracting and canceling out 2.

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

Factor

$$-\frac{1}{2} = -0.5$$
