Mom is splitting 30 cupcakes evenly between me and my friends.

If there are 3 of us, how many cupcakes should we each get?

3 columns of blocks. There are 30 blocks in total.

Each column of blocks represents one person. If there are 3 columns, that means there are 3 people. To split the cupcakes evenly, mom will divide the 30 cupcakes equally among the 3 people.

So, each person should get 30 cupcakes ÷ 3 people = 10 cupcakes.

Therefore, each person should get 10 cupcakes.
