Step 1:Let's solve this step by step:
Step 2:: Convert the total amount of flour needed to a single fraction
• Total flour needed = $$2\frac{1}{4}$$ cups
• Convert to an improper fraction: \frac{9}{4} cups
Step 3:: Determine the size of Lee's measuring cup
• Lee has a $$\frac{3}{4}$$-cup measuring cup
Step 4:: Calculate how many \frac{3}{4}-cup measures are needed
• $$\frac{9}{4} \div \frac{3}{4} = \frac{9}{4} \times \frac{4}{3} = \frac{9}{3} = 3
• Divide total flour by the size of the measuring cup
Step 5:: Verify the calculation
• $$3 \times \frac{3}{4} = \frac{9}{4}$$ cups ✓
• This matches the original amount of flour needed
Final Answer
The correct answer is A. 3.
