Anthony bought an 8 foot board. he cut off 3/4 of the board to build a shelf and gave 1/3 of the rest to his brother for an art project .how many inches long was the piece anthony gave to his brother?

The size of the board is 8 foot. From this board , 3/4 was cut to build a shelf. 1/3 from the rest was given to the brother.
original board - 8 foot
the amount cut to build a shelf - 3/4 of 8 = 3/4 x 8 = 6
The remaining part of the board - 8-6 = 2 foot
1/3 rd of the remaining part was given 
therefore 1/3 of 2 = 0.67 foot
0.67 foot long board was given to the brother 

The best description is: . nobody has any idea what q is.
