yaroslaw [1]

Answer: Each piece would be 3/4 feet long

Step-by-step explanation:

If the piece of lumber is 2 1/4 ft long, and it is cut into 3 pieces then divide

2 1/4 by 3 to find out how long each piece of cut wood would be.

2 1/4 is the same as 9/4

$\frac{9}{4} / \frac{3}{1}$ = 9/12 which also simplifies to 3/4
