Division Mixed Number
1. The problem is to evaluate the expression: 8 divided by 2 and 4/5.
2. First, interpret "2 and 4/5" as the mixed number $2 \frac{4}{5}$.
3. Convert the mixed number to an improper fraction:
$$2 \frac{4}{5} = \frac{2 \times 5 + 4}{5} = \frac{10 + 4}{5} = \frac{14}{5}$$
4. Now, the expression becomes:
$$8 \div \frac{14}{5}$$
5. Dividing by a fraction is the same as multiplying by its reciprocal:
$$8 \times \frac{5}{14}$$
6. Multiply the numerators and denominators:
$$\frac{8 \times 5}{14} = \frac{40}{14}$$
7. Simplify the fraction by dividing numerator and denominator by their greatest common divisor, which is 2:
$$\frac{40 \div 2}{14 \div 2} = \frac{20}{7}$$
8. The final answer is the improper fraction $\frac{20}{7}$, or as a mixed number:
$$2 \frac{6}{7}$$
