Answer: Waffles: Total Number of Students is 21:56. Simplified it would be 3:8.
Explanation:
First, you take the total number of students, which in this case is 56, and subtract it from the number of students who want the pancakes. The difference is 21. That is the number of students who want waffles.
The ratio is 21:56. It must be in that order. It is not the Total number of students: waffles, it is waffles: total number of students.
If it must be simplified, find the greatest common factor. In this problem, it is 7. So the simplified version is 3:8.
