Can some1 pls explain to me how to do katrina is building a deck. she cuts 3 lengths of wood from a 72-inch board. the first length is . 3. 4. inches. the second length is . 1. 4. inches. and the third length is . 1. 4. inches. how much of the original board remains after katrina makes her cuts?

Rewriting the question, the given lengths that were cut from the board were 30 3/4 inches, 12 1/4 inches, and 16 1/4 inches. To obtain the remaining length of the board, all of the measurements cut are to be added and subtracted from 72 inches. This is shown below:

30 3/4 + 12 1/4 + 16 1/4 = 237/4 = 59.25 inches.

Remaining length of board = 72 - 59.25 = 12.75 inches.

Therefore, there will be 12.75 inches remaining of the board.

The answer would be 484
