1. The problem is to simplify the expression $\frac{7n}{\epsilon} \div 5$. 2. Division by a number is the same as multiplication by its reciprocal, so we rewrite the expression as: $$\frac{7n}{\epsilon} \times \frac{1}{5}$$ 3. Multiply the numerators and denominators: $$\frac{7n \times 1}{\epsilon \times 5} = \frac{7n}{5\epsilon}$$ 4. The simplified expression is $\frac{7n}{5\epsilon}$. This means you divide $7n$ by $5\epsilon$.
