10 Multiple Answer 1 point David is trying to solve the following. If 24 people have the flu out of 360 people, how many would have the flu out of 900 ? Choose EVERY proportion that David could use to solve this problem. \( \frac{24}{360}=\frac{x}{900} \) \( \frac{900}{360}=\frac{x}{24} \) \( \frac{360}{24}=\frac{x}{900} \) \( \frac{24}{360}=\frac{900}{x} \)
