Jack has a 8-ft long board. he cut off 1/6 of it how long is the remaining piece in feet and inches

First, let's find out the equivalent amount of one-sixth of the total length of 8 ft.

Length of cut = 8(1/6) = 4/3 ft

So, the remaining length would be:
Remaining length = 8 ft - 4/3 ft = 20/3 ft or that's 6 and 2/3 ft.

Since there are 12 inches in 1 ft:
2/3 ft * 12 in/ft = 8 inches

Thus, the remaining length is 6 ft and 8 inches.
