If 2 for every 3 students are in the activity, and there are 600 total students, then you can use ratios to find how many students in this after school activity.
2:3 is the ratio we are given.
We need to find x in x:600, with 600 being the total number of students.
2:3 and x:600 must be equivalent ratios.
This means we can divide 600 by 3 and multiply that by 2 to get x.
600 / 3 = 200
2 • 200 = 400
2:3 = 400:600
2:3 and 400:600 are equivalent.
The ratio 400:600 means that 400 students out of the 600 total students participate in this after school activity.
Answer:
400 students are in this after school activity.
In ratio form:
400:600
Hope this helps!
