Question

A carpenter cut a board into three pieces. One piece was 2 5/6 feet long. The second piece was 3 1/6 feet long . The third piece was 1 5/6 feet long. How long was the board?

Answer 1

Just add these all up to get the amount for the whole board. So 3 + 1 + 2= 6 then 1/6 + 5/6 + 5/6= 11/6 = 1 5/6 + 6= 7 5/6

Answer 2

Add the individual pieces.
2 5/6 + 3 1/6 + 1 5/6 = 6 11/6
change the 11/6 to a mixed number 1 5/6
to make a total of 7 5/6
