A fifth-grade class went on a field trip to the zoo, and their class of 10 students merged with another class with the same amount of students. 5 parents offered to be a chaperone, and 2 of the teachers from both classes will be there too. When the school day was over, the students could choose to go home and 10 of them left. Two of the chaperones were parents in that group, so they left as well. How many individuals were left at the zoo? Give the rationale and then the answer.
Let's think step by step. A total of 10 * 2 = 20 students went on the field trip. Some chaperones showed up, letting the group grow to 20 + 5 = 25 individuals. The teachers had to come as well, making the group as big as 25 + 2 = 27 individuals. When the school day ended, 27 - 10 = 17 individuals were left. A couple of chaperones followed suit, leaving 17 - 2 = 15 people at the zoo.. The answer is: 15.

There are six oranges in a fruit basket. There are two fewer apples than oranges. There are 3 times as many bananas as apples, and there are half as many peaches as bananas. How many pieces of fruit are in the fruit basket? Give the rationale and then the answer.
Let's think step by step. There are 6 - 2 = 4 apples. There are 3 * 4 = 12 bananas. There is 1 / 2 x 12 bananas = 6 peaches. There is 6 oranges + 4 apples + 12 bananas + 6 peaches = 28 pieces of fruit.. The answer is: 28.

Jennifer bought twice as many candies as Emily and three times as many as Bob bought. If Emily bought 6 candies, how many candies did Bob buy? Give the rationale and then the answer.
Let's think step by step. Jennifer bought twice as many as Emily (who bought 6 candies) which is 6 * 2 = 12 candies. 12 candies (that Jennifer bought) is three times as much as what Bob bought which means 3 * what Bob bought = 12. Dividing both sides of the equation by 3 gives: Number of candies Bob bought = 12 / 3 = 4 candies.. The answer is: 4.
