[Question]Bryan bought three different bottles of milk. The bottles contain the following volumes of milk: 2 liters, 750 milliliters, 250 milliliters. How many liters of milk did Bryan buy in total?
[Answer]Bryan bought a total of 750 + 250 = 1000 milliliters of milk from the two smaller bottles. Since 1 liter is equal to 1000 milliliters, then 1000 milliliters is equal to 1000 / 1000 = 1 liter. Therefore, Bryan bought a total of 2 + 1 = 3 liters of milk. The answer is 3.

[Question]Braelynn has 24 knives in her kitchen and twice as many teaspoons as knives. If she bought 1/3 as many additional knives and 2/3 as many additional teaspoons, what would be the total number of cutlery pieces she has in her kitchen?
[Answer]Braelynn bought 1 / 3 * 24 = 8 more knives to add to her kitchen. The total number of knives in her kitchen is now 24 + 8 = 32 knives. In her kitchen, Braelynn currently has 2 * 24 = 48 teaspoons. When she buys 2 / 3 times more teaspoons, the total number increases by 2 / 3 * 48 = 32. So she will have a total of 32 + 48 = 80 teaspoons. The total number of cutlery pieces Braelynn will have in her kitchen is 80 + 32 = 112. The answer is 112.

[Question]Joe goes camping with his dad on a Friday. Joe's dad has 21 marshmallows, and Joe has four times as much marshmallows as his dad. If Joe’s dad roasts a third of his marshmallows, and Joe roasts half of his marshmallows, how many marshmallows did they roast in total?
[Answer]Joe’s dad roasts 21 / 3 = 7 of his marshmallows. Joe has 21 * 4 = 84 marshmallows. Joe roasts 84 / 2 = 42 of his marshmallows. Joe and his dad roasted 7 + 42 = 49 marshmallows in total. The answer is 49.

[Question]Jacob is making s'mores. Each s'more takes two graham crackers and one marshmallow. If Jacob has 48 graham crackers and 6 marshmallows, how many more marshmallows does he need to buy?
[Answer]
First find the number of marshmallows Jacob needs: 48 graham crackers / 2 graham crackers / marshmallow = 24 marshmallows. Then subtract the number of marshmallows Jacob already has from the number he needs to find the number he needs to buy: 24 marshmallows - 6 marshmallows = 18 marshmallows. The answer is 18.
