Question: Express $2 \frac{1}{2}$ as a mixed fraction.
1. The problem asks to express the number $2 \frac{1}{2}$ as a mixed fraction.
2. A mixed fraction consists of a whole number and a proper fraction combined.
3. The number $2 \frac{1}{2}$ is already in mixed fraction form, where $2$ is the whole number and $\frac{1}{2}$ is the fraction.
4. Therefore, $2 \frac{1}{2}$ as a mixed fraction is simply $2 \frac{1}{2}$.
5. If you want to convert it to an improper fraction, multiply the whole number by the denominator and add the numerator: $$2 \times 2 + 1 = 4 + 1 = 5$$
6. So, the improper fraction is $$\frac{5}{2}$$.
7. But since the question asks for a mixed fraction, the answer remains $2 \frac{1}{2}$.
