Solution steps

Apply the fraction rule:

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

= \frac{21}{10} \times \frac{6}{7}

Multiply fractions:

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

= \frac{21 \times 6}{10 \times 7}

21 \times 6 = 126

= \frac{126}{10 \times 7}

Multiply the numbers:

10 \times 7 = 70

= \frac{126}{70}
