Answer: 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
The easiest way to solve this problem is to make the fractions improper. 2 1/2 would be 5/2 and 4 1/5 would be 21/5.
Then you would multiply them straight across.
5*21= 105
2*5= 10
Afterward you would simplify.
105/10=10 1/2
