A group of students are meeting in the cafeteria. 70 students have already arrived. This is 35% of the group. How many students are in the group?
Responses
To solve this problem, we can use the proportion:
70 is to y as 35 is to 100
where y represents the total number of students in the group. We can cross-multiply and solve for y:
70 × 100 = 35y
7000 = 35y
y = 200
Therefore, there are 200 students in the group.
