Answer
To divide mixed numbers, convert them into improper fractions. Then switch the numerator and denominator of one of the two fractions, then multiply the numerators together and the denominators together.
Work Step by Step
For example:
$2\frac{3}{4} \div 1\frac{2}{5}$
Convert them into improper fractions
$\frac{11}{4} \div \frac{7}{5}$
Swap the numerator and denominator of one of the fractions
$\frac{11}{4} \times \frac{5}{7}$
Multiply the numerators together and the denominators together
$\frac{55}{28}$
If you want to, you can convert it back into a mixed fraction
$1\frac{27}{28}$
