We have a question: 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?
And an answer: 10
So how you got the answer?
88 / 2 = 44 dogs are playing with toys. 88 / 4 = 22 dogs are barking. 88 - 12 - 44 - 22 = 10 dogs are not doing anything.

And an answer: 1200
So how you got the answer?
There are a total of 9 + 10 + 11 = 30 kindergartners. Altogether, they bring a total of 30 x 40 = 1200 tissues.

There were 3 * 120 = 360 calories in the package. So he ate 360 / 2 = 180 calories.
