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?
Thoughts? Step-by-step reasoning:
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.
Thus, the answer is 6.
