To find the ratio of the number of students who are staying at school to the total number of students, we first need to calculate the total number of students.
-
Calculate the total number of students:
- Students going on a field trip: 34
- Students staying at school: 65
- Total number of students = 34 + 65 = 99
-
Determine the number of students staying at school:
- Students staying at school = 65
-
Calculate the ratio:
- Ratio of students staying at school to the total number of students = \( \frac{65}{99} \)
Thus, the ratio of the number of students who are staying at school to the total number of students is \( \frac{65}{99} \).
