weqwewe [10]

Answer:

1.6 cups of sugar

Step-by-step explanation:

Ashley would need 1.6 cups of sugar because she is making 4 batches of cookies, and each batch would need 0.4 cups of sugar. Therefore, you would multiply 0.4x4, which is 1.6 (don't forget the decimal point). That is why your answer would be 1.6 cups of sugar.
