<PRE><B>Question 1203072</B>
This is a proportion.  


4 turbines per 3000 homes;
How-many turbines per 25898 homes?
The two ratios are to be equal.


{{{T/25898=4/3000}}}---------solve for T.

Or looking at the ratios starting with the unaccounted turbines for the second given count of homes:


{{{25898*homes*(4/3000)(turbines/homes)}}}

{{{25898*cross(homes)*(4/3000)(turbines/cross(homes))}}}

{{{(25898*4)/3000}}}{{{turbines}}}</PRE>
