simplify

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

- \frac{1}{4}

Decimal Notation

- 0.25

Solution steps

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

Apply the fraction rule:

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

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

Multiply the numbers:

2 (- 2) = - 4

= \frac{1}{- 4}

Apply the fraction rule:

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

= - \frac{1}{4}

\frac{x ^{2} - 1}{x ^{2} - 6 x + 5} \cdot \frac{3 x - 15}{6 x}

(3 x - 5) (3 x - 5)

9 - (27)^{\frac{2}{3}}

(27 x^{9})^{\frac{2}{3}}

\frac{( x ^{3} + 3 x ^{2} + 3 x + 1 )}{( x + 1 )}
