Felicia is baking a cake. She needs 2 cups of flour, a cup of white sugar, a 1/4 cup of brown sugar, and a 1/2 cup of oil. Her only measuring scoop is 1/4 cup. How many times does she fill it to complete the measurements? Give me reasons, before answering the question
She fills it 8 times for the flour because 2 / (1 / 4) = 8. She fills it 4 times for the white sugar because 1 / (1 / 4) = 4. She fills is 2 times for the oil because (1 / 2) / (1 / 4) = 2. She fills it 1 time for the brown sugar because she needs exactly 1 / 4 of a cup. She fills is 15 times because 8 + 4 + 2 + 1 equals 15. So the final answer is 15.
