Question 633158
Joe bought a bag of oranges on Monday, and ate a third of them.
 On Tuesday he ate half of the remaining oranges.
 On Wednesday he looked in the bag to find he only had two oranges left.
 How many oranges were originally in the bag?
:
Let x = original number of oranges
:
{{{2/3}}}x, remain on Monday
{{{1/2}}}*{{{2/3}}}x = {{{1/3}}}x remain on Tuesday
{{{1/3}}}x = 2 remain on Wednesday
multiply both sides by 3
1x = 6 orange originally
