To solve this problem, we'll follow these steps:

• Step 1: Convert each mixed number to an improper fraction.
• Step 2: Multiply the improper fractions.
• Step 3: Convert the result back to a mixed number.

Now, let's work through each step:

Step 1: Convert each mixed number to an improper fraction.
For $1\frac{1}{4}$:
- Whole number is 1, denominator is 4, and numerator is 1.
- Convert to improper fraction: $1\frac{1}{4} = \frac{4 \times 1 + 1}{4} = \frac{5}{4}$.

For $1\frac{6}{8}$:
- Whole number is 1, denominator is 8, and numerator is 6.
- Convert to improper fraction: $1\frac{6}{8} = \frac{8 \times 1 + 6}{8} = \frac{14}{8}$.
- Simplify $\frac{14}{8}$ to $\frac{7}{4}$ by dividing both the numerator and the denominator by 2.

Step 2: Multiply the improper fractions:
$\frac{5}{4} \times \frac{7}{4} = \frac{5 \times 7}{4 \times 4} = \frac{35}{16}$.

Step 3: Convert the improper fraction back to a mixed number:
Divide 35 by 16. This gives 2 as the quotient with a remainder of 3.
Thus, $\frac{35}{16} = 2\frac{3}{16}$.

Therefore, the product of $1\frac{1}{4} \times 1\frac{6}{8}$ is $2\frac{3}{16}$.

To solve the problem of multiplying the mixed numbers $2\frac{5}{6}$ and $1\frac{1}{4}$, we will follow these steps:

Multiply the whole number 2 by the denominator 6, resulting in 12. Add the numerator 5 to get 17.
Thus, $2\frac{5}{6} = \frac{17}{6}$.

For $1\frac{1}{4}$:
Multiply the whole number 1 by the denominator 4, resulting in 4. Add the numerator 1 to get 5.
Thus, $1\frac{1}{4} = \frac{5}{4}$.

• Step 2: Multiply the improper fractions.

Multiply $\frac{17}{6}$ by $\frac{5}{4}$:
The result is $\frac{17 \times 5}{6 \times 4} = \frac{85}{24}$.

• Step 3: Convert the result back to a mixed number.

For $2\frac{1}{2}$:
$2\frac{1}{2} = \frac{2 \times 2 + 1}{2} = \frac{5}{2}$.

Step 2: Multiply the improper fractions:
$\frac{9}{5} \times \frac{5}{2} = \frac{9 \times 5}{5 \times 2} = \frac{45}{10}$.

Step 3: Simplify the fraction and convert it back to a mixed number:

• Convert each mixed number to an improper fraction:
  For $5 \frac{1}{7}$: Multiply the whole number 5 by the denominator 7 and add the numerator 1: $5 \times 7 + 1 = 36$. Therefore, $5 \frac{1}{7}$ becomes $\frac{36}{7}$.
  For $1 \frac{3}{4}$: Multiply the whole number 1 by the denominator 4 and add the numerator 3: $1 \times 4 + 3 = 7$. Therefore, $1 \frac{3}{4}$ becomes $\frac{7}{4}$.
• Multiply the improper fractions:
  Multiply the numerators: $36 \times 7 = 252$.
  Multiply the denominators: $7 \times 4 = 28$.
  Thus, $\frac{36}{7} \times \frac{7}{4} = \frac{252}{28}$.
• Simplify the resulting fraction, $\frac{252}{28}$:
  Divide both the numerator and denominator by their greatest common divisor, which is 28:
  $252 \div 28 = 9$ and $28 \div 28 = 1$.
  So, $\frac{252}{28} = 9$.

Therefore, the solution to the problem is $9$.

Thus, $4\frac{4}{7} = \frac{32}{7}$.

For $2\frac{1}{2}$:
Multiply the whole number by the denominator: $2 \times 2 = 4$.
Add the numerator: $4 + 1 = 5$.

Step 2: Multiply the two improper fractions:
$\frac{32}{7} \times \frac{5}{2} = \frac{32 \times 5}{7 \times 2} = \frac{160}{14}$.

Step 3: Simplify $\frac{160}{14}$ and convert to a mixed number:
First, simplify the fraction by finding the greatest common divisor of 160 and 14, which is 2.
$\frac{160}{14} = \frac{160 \div 2}{14 \div 2} = \frac{80}{7}$.

Convert $\frac{80}{7}$ to a mixed number:
Divide 80 by 7, which gives a quotient of 11 and a remainder of 3.
Thus, $\frac{80}{7} = 11\frac{3}{7}$.
