The expression in the image is:

$3\frac{2}{4} \div \frac{5}{14}$

Let's solve this step by step.

Step 1: Convert the mixed number to an improper fraction.

The mixed number $3\frac{2}{4}$ can be converted to an improper fraction.

$3\frac{2}{4} = \frac{3 \times 4 + 2}{4} = \frac{12 + 2}{4} = \frac{14}{4}$

Step 2: Simplify the fraction if possible.

$\frac{14}{4}$ can be simplified by dividing both the numerator and the denominator by 2:

$\frac{14}{4} = \frac{7}{2}$

Step 3: Rewrite the division as multiplication.

Dividing by a fraction is the same as multiplying by its reciprocal. So the expression becomes:

$\frac{7}{2} \div \frac{5}{14} = \frac{7}{2} \times \frac{14}{5}$

Step 4: Multiply the fractions.

Now, multiply the numerators and denominators:

$\frac{7 \times 14}{2 \times 5} = \frac{98}{10}$

Step 5: Simplify the result.

Finally, simplify $\frac{98}{10}$ by dividing both the numerator and the denominator by 2:

$\frac{98}{10} = \frac{49}{5}$

So, the final answer is:

$\frac{49}{5} \text{ or } 9\frac{4}{5}$
