Final answer:
You can cut 69 and 3/4 4-inch pieces of ribbon from a spool that is 279 inches long.
Step-by-step explanation:
To determine the number of 4-inch pieces of ribbon that can be cut from a spool of ribbon that is 279 inches long, we divide the total length of the ribbon by the length of each piece. In this case, we divide 279 by 4, which gives a quotient of 69 with a remainder of 3. This means that we can cut 69 whole 4-inch pieces with 3 inches of ribbon remaining, resulting in a mixed number of 69 and 3/4.
