Hi,         

Let x and (8272 -x) represent the yes votes and no votes respectively

Question Sets Up the Proportion***

 

Cross multiplying to solve for x

   4x = 7(8272-x)

  4x = 7*8272 - 7x

  11x = 7*8272

    x = 7*8272/11

    x =5264, the number of yes votes.  No votes = 3008    (8272 - 5264)



CHECKING our Answer***

 7/4 = 1.75 =  5264/3008 = 1.75
