Answer
To mulitly mixed numbers, you can convert them into improper fractions, then multiply the numerators together and the denominators together.
Work Step by Step
For example:
$1\frac{2}{3} \times 2 \frac{3}{4}$
Convert to improper fractions
$\frac{5}{3} \times \frac{11}{4}$
Multiply the numerators together and the denominators together
$\frac{55}{12}$
You can then convert it back into a mixed fraction
$4\frac{7}{12}$
