Question

out of the 31 students in the gym, 21 are sitting on the bleachers and the rest are sitting on the floor. what is the ratio of the number of students sitting on the bleachers to the total number of students? write your answer as two numbers separated by a colon (for example, 2:3).

Explanation:

Step1: Find the number of students on the floor.

Total students = 31, students on bleachers = 21. So students on floor = \( 31 - 21 = 10 \).

Step2: Find the ratio of bleachers to floor students.

Ratio is \( 21:10 \) (since 21 on bleachers, 10 on floor).

Answer:

21:10
