Answer:
2 cups
Explanation:
We see that we need 5 cups of flour for 2.5 muffins. We want to find how much flour is needed for 1 muffin. Let's set up a proportion:
, where x is how much flour is needed for 1 muffin
Cross-multiplying, we get:
2.5x = 5
x = 2
Thus, you need 2 cups of flour for one muffin.
Hope this helps!
