Lizzy: There are 88 dogs in a park. 12 of the dogs are running. Half of them are playing with toys. A fourth of them are barking. How many dogs are not doing anything?.
Me: Hmmm, let me think. I think this is the detailed solution:
88 / 2 = 44 dogs are playing with toys. 88 / 4 = 22 dogs are barking. 88 - 12 - 44 - 22 = 10 dogs are not doing anything. Final answer: 10.
