\frac{1}{30}

Solution steps

\frac{7}{45} \div \frac{42}{9}

Apply the fraction rule:

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

= \frac{7}{45} \times \frac{9}{42}

\frac{9}{42} = \frac{3}{14}

= \frac{7}{45} \times \frac{3}{14}

Multiply fractions:

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

= \frac{7 \times 3}{45 \times 14}

Multiply the numbers:

7 \times 3 = 21

= \frac{21}{45 \times 14}

Multiply the numbers:

45 \times 14 = 630

= \frac{21}{630}

Cancel the common factor:

21

= \frac{1}{30}

- 2 i - 12
