There would be 200 students in the group.
You can set up a proportion like so:
35%/100=70/x
using cross multiplication, you would get 200

Answer: 200 students

Explanation:

Let the total number of students in the group be 'x'.

35% of the group=70 students

According to the question,

35% of x =70

$\Rightarrow0.35\cdot\ x=70\\\\\Rightarrow\ x=(70)/(0.35)\\\\\Rightarrow\ x=(7000)/(35)\\\\\Rightarrow\ x=200$

Therefore, there are 200 students in the group meeting in the cafeteria .
