there are 16 friends sharing 4 cupcakes. if they divide the cupcakes evenly so that they each get four pieces of a cupcake, how many pieces do they need to cut each cupcake into

Supposedly if each cupcake was cut in 4th's, there would be 16 pieces which each person would get 1 piece. But for each person to get 4 pieces you would need to multiply 16 x 4 = 64, then 4 x 4 = 16, so you would need to cut each cupcake in 16th's
