标题:
recall another math problem
it was an easy one but need to be careful
a box of fuits(maybe vegetables,whatever), 1/5 are peaches, 1/3 of which are unusable,what is the fraction of peaches that are usable?
Pay attention to "unusable" and "usable"...thank god i noticed the
difference just before i confirmed it.
