Tom has only been getting 6 hours of sleep a day. He increases that by 1/3. How many hours of sleep does he get per night?
Let's think: He increases his sleep by 6 / 3 = 2 hour per night. So he now gets 6 + 2 = 8 hours of sleep per night.. The answer is: 8.

Brad wanted to set up a lemonade stand to earn some money. Every gallon of lemonade would yield 16 glasses. He figured it would cost him $3.50 to make every gallon of lemonade. He made 2 gallons to sell and decided he would sell each glass for $1.00 He drank 5 glasses while sitting in his stand. He sold all but 6 glasses of lemonade. How much net profit did Brad earn?
Let's think: He made 2 gallons and each gallon had 16 glasses so 2 * 16 = 32 glasses. He drank 5 glasses and had 6 left over which means he would not earn money on 5 + 6 = 11 glasses. The total revenue would come from 32 - 11 = 21 glasses. Each gallon cost $3.50 to make so the total cost was 2 * 3.50 = $7.00. He sold 21 glasses at $1.00 per glass for a total of 1 * 21 = $21.00. When you take his earnings of $21.00 and subtract the cost of $7.00 his total net profit was 21 - 7 = $14.00.. The answer is: 14.

Two friends are racing three miles. The first one runs it in 21 minutes. The second one runs it in 24 minutes. If they keep up the same pace, how long combined will it take for them to run 5 miles each?
Let's think: The first one runs a mile in 7 minutes because 21 / 3 = 7. The second runs a mile in 8 minutes because 24 / 3 = 8. The first one would finish 5 miles in 35 minutes because 5 x 7 = 35. The second one would finish in 40 minutes because 5 x 8 = 40. It will take 75 minutes in total because 35 + 40 = 75.. The answer is: 75.

Madison takes her dog to the dog park. Counting Madison's dog, half the dogs have spots and 1/5 have pointy ears. If 15 dogs have spots, how many have pointy ears?
Let's think:
First double the number of dogs with spots to find the total number of dogs: 15 dogs * 2 = 30 dogs. Then multiply that number by 1 / 5 to find the number that have pointy ears: 30 dogs * 1 / 5 = 6 dogs.. The answer is: 6.
