simplify (2(-1/2)^2)/((-1/2)^2-1)

simplify

\frac{2 ( - \frac{1}{2} ) ^{2}}{( - \frac{1}{2} ) ^{2} - 1}

- \frac{2}{3}

Decimal Notation

- 0.66666 \dots

Solution steps

\frac{2 ( - \frac{1}{2} ) ^{2}}{( - \frac{1}{2} ) ^{2} - 1}

Simplify

2 (- \frac{1}{2})^{2} : \frac{1}{2}

= \frac{\frac{1}{2}}{( - \frac{1}{2} ) ^{2} - 1}

Simplify

(- \frac{1}{2})^{2} - 1 : - \frac{3}{4}

= \frac{\frac{1}{2}}{- \frac{3}{4}}

Apply the fraction rule:

\frac{a}{- b} = - \frac{a}{b}

= - \frac{\frac{1}{2}}{\frac{3}{4}}

Apply the fraction rule:

\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a \cdot d}{b \cdot c}

\frac{\frac{1}{2}}{\frac{3}{4}} = \frac{1 \cdot 4}{2 \cdot 3}

= - \frac{1 \cdot 4}{2 \cdot 3}

Cancel

- \frac{1 \cdot 4}{2 \cdot 3} : - \frac{2}{3}

= - \frac{2}{3}
