Answer 3

To solve the expression $\frac{11 \frac{2}{5} \times 2 \frac{4}{7}}{4 \frac{1}{4}}$, you can follow these steps:

1. Convert the mixed numbers to improper fractions. $11 \frac{2}{5} = \frac{57}{5}$ $2 \frac{4}{7} = \frac{18}{7}$ $4 \frac{1}{4} = \frac{17}{4}$

2. Rewrite the expression with the improper fractions: $\frac{\frac{57}{5} \times \frac{18}{7}}{\frac{17}{4}}$

3. Invert and multiply (divide by a fraction is the same as multiplying by its reciprocal): $\frac{57}{5} \times \frac{18}{7} \div \frac{17}{4}$

4. Multiply the fractions: $\frac{57 \times 18}{5 \times 7} \div \frac{17}{4}$

5. Calculate the products in the numerator and denominator: $\frac{1026}{35} \div \frac{17}{4}$

6. To divide fractions, multiply by the reciprocal of the divisor: $\frac{1026}{35} \times \frac{4}{17}$

7. Multiply the numerators and denominators: $\frac{1026 \times 4}{35 \times 17}$

8. Calculate the numerator and denominator separately: $\frac{4104}{595}$

So, $\frac{11 \frac{2}{5} \times 2 \frac{4}{7}}{4 \frac{1}{4}}$ is equal to $\frac{4104}{595}$, which cannot be simplified further.
