= \frac{18}{1} \div \frac{6}{7}

Apply the fraction rule:

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

= \frac{18}{1} \times \frac{7}{6}

Cross-cancel common factor:

6

= \frac{3}{1} \times \frac{7}{1}

Multiply fractions:

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

= \frac{3 \times 7}{1 \times 1}

Multiply the numbers:

3 \times 7 = 21

= \frac{21}{1 \times 1}

Multiply the numbers:

1 \times 1 = 1

= \frac{21}{1}

Apply rule

\frac{a}{1} = a

= 21

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