Word problem solving - what am I doing wrong?

"After election results of 378 votes were tallied, the new student-body president won by a margin of 5 to 4. How many votes did she get?" I set it up as 5/4 = x/378. I multiplied both sides by 378 and finished with 1890/4. I divided by 4 and got 472.5 = x, however the answer is 210. What'd I do wrong?
