Problem of the Week - Lower Elementary - Oct. 25, 2020 to Oct. 31, 2020

Lower Elementary:

Question: Tori has reading homework that is 19 pages long. The homework is printed front-and-back on sheets of paper. How many sheets of paper are needed for the whole reading assignment?

Answer: 10 sheets of paper

Solution: Since 2 pages can go on each sheet of paper, that means that the first 18 sheets of paper can fit on half of 18 = 9 sheets of paper. The 19th page goes on a 10th sheet of paper. So, 10 pieces of paper are needed for the whole reading assignment.
