I need to understand how to do the problem and not the answer.
P.S. bobpursley, no offense but I didn't understand what your response meant. That information I already know but I need to know how to do the problem to get 213 as the answer.
Anida won the class election by margin of 53. She received 355 votes. How many votes did the other candidates get? Answer:213

Another way to solve this problem is to set up a proportion.
5 / 3 = 355 / x
Cross multiply:
5x = 1065
x = 213
