To multiply mixed numbers, we first convert them to improper fractions.<br /><br />$4\frac {3}{4} = \frac{4 \times 4 + 3}{4} = \frac{19}{4}$<br /><br />$1\frac {2}{5} = \frac{1 \times 5 + 2}{5} = \frac{7}{5}$<br /><br />Now, we multiply the two improper fractions:<br /><br />$\frac{19}{4} \times \frac{7}{5} = \frac{19 \times 7}{4 \times 5} = \frac{133}{20}$<br /><br />To convert the improper fraction back to a mixed number, we divide the numerator by the denominator:<br /><br />$\frac{133}{20} = 6\frac{13}{20}$<br /><br />Therefore, $4\frac {3}{4}\times 1\frac {2}{5} = 6\frac{13}{20}$.
