1. The problem is to find the solution and answer for the division $\frac{7}{3.5}$.\n\n2. The formula for division is $\frac{a}{b}$ where $a$ is the numerator and $b$ is the denominator.\n\n3. To simplify $\frac{7}{3.5}$, we can multiply numerator and denominator by 10 to eliminate the decimal in the denominator:\n$$\frac{7}{3.5} = \frac{7 \times 10}{3.5 \times 10} = \frac{70}{35}$$\n\n4. Now simplify $\frac{70}{35}$ by dividing numerator and denominator by their greatest common divisor, which is 35:\n$$\frac{\cancel{70}^{2 \times 35}}{\cancel{35}^{1 \times 35}} = \frac{2}{1} = 2$$\n\n5. Therefore, the solution to $\frac{7}{3.5}$ is $2$.
