Solution steps

\frac{2}{21} \div \frac{2}{6}

Apply the fraction rule:

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

= \frac{2}{21} \times \frac{6}{2}

Multiply fractions:

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

= \frac{2 \times 6}{21 \times 2}

= \frac{2}{7}

(- 8 - 3) (- 9 + 3)

\frac{3 x ^{2} - 12 x ^{3}}{3 x ^{4}}

[(3 x)^{2}]^{- 2}

(x - 5)^{2} - 2 (x - 5)

\frac{4}{3 - 1}
