Question

A 13 and one fourth inch board is cut from a 38 and three fourths inch board. The saw cut takes three eighths inch. How much of the 38 and three fourths inch board is left after​ cutting?

Answer 1

Explanation:

A 13 and one fourth inch board is cut and the saw cut takes three eighths inch. So total length from cut = 13 1/4 + 3/8 = 13 5/8 inch.

Original board is 38 and three fourths inch.

So after cutting, there is 38 3/4 - 13 5/8 = 25 1/8 inch left in the original board.

Answer 2

There is 25 1/8 inches left

Explanation:

We have a board that is 38 3/4 inches

We cut away 13 1/4

38 3/4

-13 1/4

-----------

25 2/4

The saw takes 3/8

25 2/4

- 3/8

-------------

Get a common denominator of 8 2/4 * 2/2 = 4/8

25 4/8

- 3/8

-------------

25 1/8

There is 25 1/8 inches left
