Question: There are 24 marbles in a jar. Half are blue. There are 6 red marbles. The rest of the marbles are orange. How many orange marbles are there?

Question: Patty decides that to convince her brother and sister to do her chores in exchange for cookies. Patty agrees to give them 3 cookies for every chore they do. Each kid normally has 4 chores to do per week. Patty has $15 to buy cookies. Each pack of cookies contains 24 cookies and costs $3. How many weeks can Patty go without doing chores by paying her siblings with cookies?
Answer: Patty can buy 5 packs of cookies because 15 / 3 = 5. Patty gets 120 cookies because 5 x 24 = 120. Patty would need to pay 12 cookies per week because 3 x 4 = 12. Patty can avoid 10 weeks of chores because 120 / 12 = 10. The answer is 10.

Question: John and Yasmin's dad is named Gabriel. If John has twice the number of children that her sister has and Gabriel has six grandkids, how many children does Yasmin have?
Answer: We don't know Yasmin's number of children yet, but let's represent it as Y. If John has twice the number of children Yasmin has, then John has 2 * Y = 2Y kids. If Gabriel has 6 grandkids between John's and Yasmin's children, then we can represent this as 6 = 2Y + Y. If we solve the latest equation then we learn that 6 = 3Y. Given that Y represents how many kids Yasmin has, then solving for Y we know that Y = 6 / 3 or Y = 2 kids. The answer is 2.

Question: A father and a son start approaching each other at the same time from opposite ends of a hallway that is 16m long. If the father is walking three times as fast as the son, at what distance from the father's end of the hallway will they meet?
Answer:
Since the father is walking 3 times as fast as his son, their speeds are in a ratio of 3:1 respectively. They started at the same time so they will cover distance at the same ratio of 3:1. Each portion of the distance they covered is 16 / (3 + 1) = 4m. The father covered three portions of the distance which is 3 * 4m = 12m from his end. The answer is 12.
