Question: User: switch numerator and denom
1. The problem is to switch the numerator and denominator of a fraction.
2. The formula for a fraction is $$\frac{a}{b}$$ where $a$ is the numerator and $b$ is the denominator.
3. Switching numerator and denominator means creating the reciprocal: $$\frac{b}{a}$$.
4. For example, if the fraction is $$\frac{3}{4}$$, switching numerator and denominator gives $$\frac{4}{3}$$.
5. This operation is called finding the reciprocal of a fraction.
6. Important rule: The denominator $a$ must not be zero because division by zero is undefined.
7. So, switching numerator and denominator of $$\frac{a}{b}$$ results in $$\frac{b}{a}$$, provided $a \neq 0$.
Final answer: The switched fraction is $$\frac{b}{a}$$.
