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 work this out in a step by step way to be sure we have the right answer.
6
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.

.

So, the final answer is 6
