Answer this question:Alice is making a big stack of dishes to see how tall she can make it before it topples over and falls. She starts off by placing 27 plates on top of each other. The tower holds fine so she adds 37 more plates. She is in the process of placing more and more plates when it finally topples over and crashes down, all 83 plates. How many more was Alice able to add before the tower fell and crashed?
Alice was able to stack 27 + 37 = 64 plates she already stacked. The tower crashes when there are 83 plates - 64 plates already stacked = 19 plates she was able to stack before the tower crashed.
The answer is 19.

Answer this question:A lumberjack is chopping down trees so he can sell firewood. Each tree he chops produces 4 logs each, and each log is then chopped into 5 pieces of firewood. If the lumberjack has chopped 500 pieces of firewood, how many trees did he chop down?
The firewood is made from 500 pieces of firewood / 5 pieces of firewood per log = 100 logs. So the logs are chopped from 100 logs / 4 logs per tree = 25 trees.
The answer is 25.

Answer this question:Ezekiel hikes as a hobby. This past summer, he did a challenging three-day hike across 50 kilometers of wilderness. The first day, he covered 10 kilometers of steep mountainside. The second day was flatter and he was able to cover half the full hike distance. How many kilometers did he have to hike on the third day to finish the hike?
After the first day, Ezekiel had 50 - 10 = 40 kilometers of the hike left. On the second day, he covered 50 / 2 = 25 kilometers. Therefore, on the third day, he had 40 - 25 = 15 kilometers left to finish the hike.
The answer is 15.
