If a recipe requires 3 cups of flour for 4 servings, how many cups are needed for 10 servings?

Step 1: Identify how many cups of flour are needed for the original number of servings. The recipe needs 3 cups of flour for 4 servings.
Step 2: Find out how much flour is needed for 1 serving. To do this, divide the total cups of flour by the number of servings: 3 cups ÷ 4 servings = 0.75 cups per serving.
Step 3: Now, calculate how much flour is needed for 10 servings. Multiply the amount of flour needed for 1 serving by 10: 0.75 cups × 10 servings = 7.5 cups.
Step 4: Conclude that for 10 servings, you need 7.5 cups of flour.
