Final answer:
To find the remaining width, we need to subtract 1 1/4 inches from 3 3/8 inches. The remaining width is 2 1/2 inches.
Step-by-step explanation:
To find the remaining width, we need to subtract 1 1/4 inches from 3 3/8 inches. To do this, we need to convert both measurements to a common denominator. The common denominator for 4 and 8 is 8. So, we have 3 3/8 = 3 6/8, and 1 1/4 = 1 2/8. Subtracting 1 2/8 from 3 6/8, we get 2 4/8, which simplifies to 2 1/2 inches.
