- \frac{3}{4}

Solution steps

\frac{3}{8} \div \frac{- 1}{2}

Apply the fraction rule:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{3}{8} \times \frac{2}{- 1}

Cross-cancel common factor:

2

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

Multiply fractions:

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

= \frac{3 \times 1}{4 ( - 1 )}

Remove parentheses:

(- a) = - a

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

Multiply the numbers:

3 \times 1 = 3

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

Multiply the numbers:

4 \times 1 = 4

= \frac{3}{- 4}

Apply the fraction rule:

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

= - \frac{3}{4}

(x + 2 y + 3 z)^{4}

\frac{2 + 3 i}{4 + 5 i}

75 x - 27 x

\frac{- 2}{5} + \frac{3}{8}

4 x^{2} - 27 x + 167 - \frac{996}{x - 6}
