Answer:
4 feet 2 inches
Step-by-step explanation:
Total Ribbon = 75 feet
Total Students = 18
If equally cut, each student will get the total divided by number of students, that would be:
75/18
That would be:
feet per student
Now, we need the fractional part as inches.
We know 12 inches is 1 feet, so 1/6th feet is:
The fractional part is "2 inches"
Thus,
each piece would be <u>4 feet 2 inches</u>
