Question

At our school, 2 out of 3 students is involved in an after school activity. How many of the 600 students are in an after school activity at our school?

1 Answer

  • 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!
