Explanation:

Hello, I can help you with this

you can solve this using a simple rule of three

Let

210 teenagers ⇒ (4/5) of all teenagers

x teenagers ⇒ 1 of all teenagers

`(210\ teenagers )/((4/5) of\ all\ teenagers)=(x\ teenagers)/(1\ all\ the\ teenagers) \\ solve for x\\x=(1\ all\ the\ teenagers*210\ teenagers )/((4/5) of\ all\ teenagers)\\x=(210)/((4/5))\teenagers\\ x=(210*5)/(1*4)\\x=(1050)/(4)\\x=262.5\\` teenagers

we need take the whole number because the unit is teenagers

x=263

the maximum number of teenagers who live in geotown is 263
