Mrs. Neltner is baking 4 batches of chocolate cupcakes. She needs 1 2/6 cups of cocoa for each batch of cupcakes. Mrs. Neltner calculated how many cups of cocoa she'd need by creating and solving the equation below.
4 x 1 2/6= 4 x 9/6= 36/6= 6 cups
What was Mrs. Neltner's error?
What is 1 2/6 is not the same as 9/6, but instead it is actually 8/6.
