Divide 7 1/2 by 2 1/2.

Explanation:
Dividing by a mixed number means multiplying by its reciprocal after turning both numbers into improper fractions. Convert 7 1/2 to 15/2 and 2 1/2 to 5/2. Then (15/2) ÷ (5/2) is (15/2) × (2/5). The 2 cancels, giving 15/5 = 3. Another way to see it is: how many times does 2 1/2 fit into 7 1/2? Three times, since 3 × 2 1/2 = 7 1/2. The result is 3.
