The remaining length of the board is 8 11/12 feets
Length of board = 12 1/4 feets
Length that was cut off = 3 1/3 feets
To obtain the length of the remaining part of the board ;
We subtract the length that was cut off from the total length of the board ;
(Total length - length that was cut off)
12 1/4 = 49/4
3 1/3 = 10/3
(49/4 - 10/3) =
L. C. M of 4 and 3 = 12
(147 - 40) / 12 = 107 / 12
107 / 12 = 8 11/12 feets
The remaining length of the board is 8 11/12 feets
