Your project requires a board that has a length of 5 3/16 inches. You found a board that has a length of 9 1/8 inches. How much of the board needs to be cut to use if for your project? Inches

3 + 15/16 inches

Step-by-step explanation:

You need (5 + 3/16) inches, and you have (9 + 1/8) inches, then the amount that you need to cut is equal to the difference between these numbers, this is:

(9 + 1/8) - (5 + 3/16) = (9 - 5) + (1/8 - 3/16) = 4 + (2/16 - 3/16) = 4 - 1/16

now, this notation is used for aditions, so we can write it as:

4 - 1/16 = 3 + 1 - 1/16 = 3 + 16/16 - 1/16 = 3 + 15/16

Then the amount that needs to be cuted is 3 + 15/16 inches

what's that
