Explanation:

7070 students arrived at the cafeteria. But that doesn't mean there are only 70 students. The rest are still behind. That 7070 students are 35%35% of the group. Now they ask us to find the amount of students are there in total.

35%..........70
100%.........x

Cross multiply

(35)(x) = (70)(100)

35x= 7000

Divide both sides by 35

(cancel35x)/cancel35= 7000/35

x=200

Thus,

There are 200 students in the group!
