1. The problem asks: Quinn divides 40 by 9. Between what two whole numbers is the answer? 2. To find the answer, we perform the division: $$\frac{40}{9}$$. 3. Divide 40 by 9: $$40 \div 9 = 4 \text{ remainder } 4$$ 4. This means $$\frac{40}{9} = 4 + \frac{4}{9}$$. 5. Since $$\frac{4}{9}$$ is less than 1, the quotient is between 4 and 5. 6. Therefore, Quinn's answer is between the whole numbers 4 and 5. Final answer: 4 and 5.
