Answer 3

To solve the inequality $2 \frac{3}{7} < \frac{x}{7} < 3 \frac{1}{7},$ you can follow these steps:

Step 1: Subtract $2 \frac{3}{7}$ from all parts of the inequality:

$$2 \frac{3}{7} - 2 \frac{3}{7} < \frac{x}{7} - 2 \frac{3}{7} < 3 \frac{1}{7} - 2 \frac{3}{7}.$$

This simplifies to:

$$0 < \frac{x}{7} - 2 \frac{3}{7} < 0.$$

Step 2: Now, we want to isolate $\frac{x}{7} - 2 \frac{3}{7}$ in the middle:

$$0 < \frac{x}{7} - 2 \frac{3}{7}.$$

Step 3: Add $2 \frac{3}{7}$ to both sides of the inequality:

$$2 \frac{3}{7} < \frac{x}{7}.$$

Step 4: Finally, multiply both sides of the inequality by 7 to isolate $x$:

$$7 \cdot 2 \frac{3}{7} < 7 \cdot \frac{x}{7}.$$

Simplifying:

$$\frac{22}{1} < x.$$

So, the solution to the inequality $2 \frac{3}{7} < \frac{x}{7} < 3 \frac{1}{7}$ is $x > \frac{22}{1}$ or simply $x > 22$.
