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?

Convert your feet to inches.

So 8 times by 12 = 96 inches

if you have 3/4 of the board used.

3/4 =.75

if you were to times 96 by. 75 = 72 inches.

So you used 72 inches and you have 24 inches left

now do 1/3 =.33

times. 33 by 24 = 8

8 inches is how long you would give to Anthony's brother.

Or you could just make the denominators both to 12 then subtract them and get the answer 5/12
