Set up a ratio of Yes votes compared to Total votes cast. If the ratio of yes votes to no votes was 3 to 2, then there were 3 yes votes cast for every 5 total votes. Set up the following ratio:
%28Yes%29%2F%28Total%29+=+3%2F5+=+2124%2Fx

Now, since a%2Fb=c%2Fd means that ad=bc,
3%2F5+=+2124%2Fx means taht 3x+=+5%2A2124
3x+=+10620
x=3540 total votes cast.
