Question

Jasper kept track of the trick-or-treaters who came to his door and found that 1/4 were dressed as ghosts and 5/12 were dressed as witches. What fraction of the trick-or-treaters were dressed as either ghosts or witches?

Answer 1

8/12 or 1/3

Because you have to make 5/12 and 1/4 equal. 1/4=3/12. 5/12+3/12= 8/12.
