Jordan is baking cookies and he needs to adjust his recipe. The original recipe calls for 2.5 cups of flour, but he only has a 0.75 cup measuring cup. He will use this measuring cup exclusively to measure out the flour.
If Jordan wants to use the correct amount of flour, how many times does he need to fill the 0.75 cup measuring cup to get exactly 2.5 cups of flour?
