8 inches is +8%2F12+=+2%2F3+ ft
3 ft is +9%2F3+ ft
+9%2F3+%2B+2%2F3+=+11%2F3+
+4%2A%2811%2F3%29+=+44%2F3+
+44%2F3+=+14+%2B+2%2F3+
This is more than 14 ft, so the shortest board
that will work is 15 ft

a carpenter needs to cut four sections each 3 feet 8 inches long from a piece of board. if the board is only sold by the foot what's the shortest length of board she can buy?
================
Comment: 8 inches is 8/12 = 2/3 ft
------------------
4(3 2/3) = 4*(11/3) = 44/3 = 14 2/3 feet (length of the board)
OR
4(3 2/3) = 4*3 + 4*(2/3) = 12 + 8/3 = 12 + 2 + 2/3 = 14 2/3 feet
