Why does 1/2 + 1/3 NOT equal 1/5? 1/5 is a smaller piece than 1/2 or 1/3 because 5 pieces of pie will be smaller than two or three. the more pieces you have the smaller the pieces are.

1/3 and 1/2 =5/6. I took a clock and put in 1/3 which is the same as 4/12.
Then I brought a line directly across for 1/2 and got 6/12. I added 6/12 and 4/12 and got 10/12 and reduced it to 5/6.So that is the real answer.
