Ms. Williams asked her class if they prefer doing their homework before school to students who prefer doing homework after school is 7:15 what does the ratio 7/22

Answer:
The number of students that prefer to do homework from the group of all students
Step-by-step explanation:
The question says that the ratio between the student who prefer doing homework before school and the students who prefer doing homework after school is 7:15.
That means 7 students prefer doing homework before school and 15 students prefer doing after school.
In this scenario, the total number of students is 7 + 15 i.e. 22
So the percentage 7/22 is the number of students that prefer to do homework before school from the group of all students
