Let's solve the expression step by step.
First, we need to convert the mixed numbers to improper fractions.
$$4 \frac{5}{6} = \frac{4 \times 6 + 5}{6} = \frac{24 + 5}{6} = \frac{29}{6}$$
$$2 \frac{1}{3} = \frac{2 \times 3 + 1}{3} = \frac{6 + 1}{3} = \frac{7}{3}$$
Now, we can multiply the two fractions:
$$\frac{29}{6} \times \frac{7}{3} = \frac{29 \times 7}{6 \times 3} = \frac{203}{18}$$
Now, we need to convert the improper fraction back to a mixed number.
$$\frac{203}{18} = 11 \frac{5}{18}$$
To find the whole number part, we divide 203 by 18:
$$203 \div 18 = 11$$ with a remainder of 5.
So, the mixed number is 11 and 5/18.
Answer: 11 5/18
