1. **Stating the problem:** For problem 9, we have a fraction $\frac{3}{4}$ on the left and the number 20 on the right of a U-shaped graph with a square box inside near the right side. 2. **Understanding the problem:** The problem likely involves finding the value represented by the square box inside the U-shape using the given fraction and number. 3. **Formula and rules:** If the fraction $\frac{3}{4}$ represents a part of the total 20, then the value inside the box can be found by multiplying the fraction by the total number. 4. **Calculation:** $$\text{Value in box} = \frac{3}{4} \times 20$$ 5. **Intermediate step with cancellation:** $$\frac{3}{\cancel{4}} \times \frac{\cancel{20}}{1} = 3 \times 5 = 15$$ 6. **Final answer:** The value inside the square box is **15**.
