+%282%2F5%29%2A125+=+50+ can sing
-----------------------
+125+-+50+=+75+ are left
+%282%2F5%29%2A75+=+30+ are good at sports
-----------------------
+20%2F30+=+2%2F3+ is the ratio of
students who can dance to the number of
students who are good at sports
-----------------------
I'm not sure if this is a trick question or not,
because it is not telling you if any of
the students who can dance are also
good at sports, which would change
the answer. That might be trying to read
too much into it
