There is 19 1/8 inches left
Step-by-step explanation:
We have a board that is 38 1/4 inches
We cut away 18 3/4
38 1/4
-18 3/4
We need to borrow 38 becomes 37 and 1/4 gets the 1 and 4/4 + 1/4 = 5/4
38 1/4
-18 3/4
We need to borrow because 7 is less than 8 2 becomes 1 and 7 becomes 17
2 17 5/4
-1 8 3/4
1 9 2/4
The saw takes 3/8
19 2/4
- 3/8
Get a common denominator of 8 2/4 * 2/2 = 4/8
19 4/8
- 3/8
19 1/8
There is 19 1/8 inches left
