**Question:** How many sets of \( \frac{3}{4} \) are in \( 2 \frac{1}{2} \)?

To find out how many sets of \( \frac{3}{4} \) are in \( 2 \frac{1}{2} \), you need to divide \( 2 \frac{1}{2} \) by \( \frac{3}{4} \).

1. **Convert Mixed Number to Improper Fraction:**
   \( 2 \frac{1}{2} = \frac{5}{2} \)

2. **Division of Fractions:**
   To divide by a fraction, multiply by its reciprocal.
   \[
   \frac{5}{2} \div \frac{3}{4} = \frac{5}{2} \times \frac{4}{3} = \frac{5 \times 4}{2 \times 3} = \frac{20}{6} = \frac{10}{3}
   \]

3. **Simplify the Fraction:** 
   \( \frac{10}{3} \approx 3 \frac{1}{3} \)

So, there are \( 3 \frac{1}{3} \) sets of \( \frac{3}{4} \) in \( 2 \frac{1}{2} \).
