210 = 4/5 (This means that 4 out of five people (210 people) are a teenager)
Then you divide 210 by the numerator to get 1/5 people:
210 / 4 = 52.5
Then you can multiply the 1/5 people (52.5) by 5 to get 5/5:
52.5 * 5 = 262.5 (rounded to 262)
Thus the maximum amount of teenagers in Geotown is 262.
Hope this helps! :)
