Question: There are 28 students in a classroom. Half of them have 5 notebooks each and the other half have 3 notebooks each. How many notebooks in total are in the classroom?
Answer: Step-by-step reasoning process: Half of the class consists of 28 students / 2 = 14 students. One half of the students have 14 students * 3 notebooks / student = 42 notebooks. The other half have 14 students * 5 notebooks / student = 70 notebooks. There are 42 notebooks + 70 notebooks = 112 notebooks in total in the classroom.
So the answer is 112.

Question: Lucille is wondering who has the tallest house between her and her neighbors. His family's house is 80 feet tall. One neighbor's house is 70 feet tall. Another neighbor's house is 99 feet tall. How much shorter is Lucille's house than the average height?
Answer: Step-by-step reasoning process: The houses are 249 feet in total because 70 + 80 + 99 = 249. The average height is 83 feet because 249 / 3 = 83. Her house is 3 feet shorter because 83 - 80 = 3.
So the answer is 3.

Question: If 1 ounce of Dawn liquid soap can make 200,000 bubbles, and Dr. Bronner's liquid soap can make twice as many bubbles per ounce as Dawn liquid soap, then how many bubbles can be made from one half ounce of an equal mixture of Dawn and Dr. Bronner's liquid soaps?
Answer: Step-by-step reasoning process: One half of a 1 / 2 - ounce liquid is (1 / 2) * (1 / 2) = 1 / 4 ounces. 1 / 4 ounce of Dawn liquid soap can make (1 / 4) * 200,000 = 50,000 bubbles. 1 / 4 ounce of Dr. Bronner's liquid soap can make 2 * (1 / 4) * 200,000 = 100,000 bubbles. Therefore, a half ounce of an equal mixture of Dawn and Dr. Bronner's liquid soaps can make 50,000 + 100,000 = 150,000 bubbles.
So the answer is 150000.
