Question

Sandy is working with a carpenter to frame a house they are using 8 foot long boards but each board must be cut to be 7 feet 10 3/4 inches long how much is cute off the board

Answer 1

Subtract 7 ft 10 3/4 inches from 8 ft 0 inches:

8 ft 0 inches
- 7 ft 10 3/4 inches
-------------------------

Since we cannot subtract 10 3/4 inches from 0 inches, borrow 12 inches (1 ft) from 8 ft 0 inches:

7 ft 12 inches
-7 ft 10 3/4 inches
--------------------------
1 1/4 inches (answer)
