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

For this case we have to know the number of pieces in which each cupcake must be cut, so that each friend has four pieces of cupcake. So:

IF they are 16 friends and each one must have four pieces of cupcake, we have the following multiplication:

64 pieces of cupcakes are needed.

Now, if we only have 4 cupcakes, we should know how many pieces each should be chopped to get 64 pieces of cupcake. So:

Let "x" be the variable that defines the amount of pieces in which each cupcake should be chopped:

By clearing "x" we have:

So, each cupcake should be cut into 16 pieces so that each friend has 4 pieces of cupcake

Each cupcake should be cut into 16 pieces so that each friend has 4 pieces of cupcake
