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?
First double the number of dogs with spots to find the total number of dogs: 15 dogs * 2 = 
<gadget id="calculator">15*2</gadget>
<output>30</output>
30 dogs.
Then multiply that number by 1/5 to find the number that have pointy ears: 30 dogs * 1/5 = 
<gadget id="calculator">30*1/5</gadget>
<output>6</output>
6 dogs.
