Ms. williams asked her class if the prefer doing their homework before school or afterschool. if the ratio of students who prefer doing homework before school to students who prefer doing homework afterschool is 7: 15, what does the ratio 7/22 represent? explain.

The given ration (7:15) means that there are 7 students who prefer doing homework before school and 15 students who prefer doing homework after school.

If you add 7+15= 22 you get the total number of students in the class.

Therefore, the ratio 7/22 will represent what part of the class prefers doing homework before school. You can express it as a percentage, as well: 
7/22 = 0.32 which means 32%.

Ithink its 126 hope its
