Q: As firefighters, Doug, Kai, and Eli have been putting out a lot of fires over the week. Doug has put out 20 fires for the week and Kai has put out 3 times more than Doug. Meanwhile, Eli has put out half the number of fires Kai was able to. How many fires have they put out for the entire week?
A: 110
Step-by-step reasoning process: Kai has put out 20 x 3 = 60 fires for the week. Eli has put out 60 / 2 = 30 fires for the week. Therefore, the total amount of fires they have put out over the entire week was 20 + 60 + 30 = 110.

Q: Anna is making gingerbread cookies. She gives 6 of them red hats, 9 of them blue boots, and 3 of them both red hats and blue boots. What percentage of the gingerbread men have red hats?
A: 50
Step-by-step reasoning process: The first step to find the total number of gingerbread men is to add the number with each decoration: 6 men + 9 men = 15 men. Then subtract the number of gingerbread men with both decorations to find the total number of gingerbread men: 15 men - 3 men = 12 men. Then divide the number of gingerbread men with red hats by the total number and multiply by 100% to express the answer as a percentage: 6 men / 12 men * 100% = 50%.

Q: A chocolate bar weighs 125 g. A shopkeeper has just received a 2 kilogram box of chocolate. How many bars does this represent?
