Tom had a board that was 4 ft. 5 in. long. He cut off a piece that was 1 ft. 9 in. long. How

much board does he have left?

1 foot = 12 inches so;

4 ft 5 in = 3 ft (12+5) in = 3 ft 17 in
so
3 ft 17 in - 1 ft 9 in = 2 ft 8 in

4 5/12 - 1 9/12 = 53/12 - 21/12 = 32/12 = 2 8/12 = 2 ft. 8 in.

To find out how much board Tom has left, we need to subtract the length of the piece he cut off from the original length of the board.

The original length of the board is 4 ft 5 in, which can be written as 4' 5".

The length of the piece Tom cut off is 1 ft 9 in, which can be written as 1' 9".

To subtract these two measurements, we need to make sure the units (feet and inches) are consistent. Let's convert both measurements to inches:

Original length: 4' 5" = (4 * 12) + 5 = 48 + 5 = 53 inches.
Length of the piece cut off: 1' 9" = (1 * 12) + 9 = 12 + 9 = 21 inches.

Now, we can subtract the length of the piece cut off from the original length:
53 inches - 21 inches = 32 inches.

Therefore, Tom has 32 inches of board left.

To find how much board Tom has left, we need to subtract the length of the piece he cut off from the original length of the board.

First, let's convert the measurements to a consistent unit. Since both measurements are in feet and inches, we'll convert them to inches for easier calculation.

The length of the board is 4 ft. 5 in., which is equivalent to (4 * 12) + 5 = 53 inches.

The length of the piece he cut off is 1 ft. 9 in., which is equivalent to (1 * 12) + 9 = 21 inches.

To find how much board Tom has left, we subtract the length of the cut-off piece from the original length: 53 inches - 21 inches = 32 inches.

Therefore, Tom has 32 inches of board left.
