Answer:
3.5
Step-by-step explanation:
Ratio of
those who walk : those who ride = 2 : 7
This means that for every 2 students who walk, there are 7 students who ride
Therefore, for every 1 student that walks, (hypothetically) there are 3.5 (7/2) students who ride
Then the number of bus riders is 3.5 times the number of students that walk.
