Na local election between candidate a and candidate b, candidate b got 35 votes, which is 125% as many votes as candidate a. if p represents number of votes won by candidate a, then which proportion can be used to find p?

Number of votes won by A = p
Number of votes won by B = 35

Number of votes won by B are 125% of the number of votes won by A. So we can write that 35 is 125% of p. In equation form we can translate it as:

35 = 125% of p 
35 = 1.25 x p 
p = 35/1.25
p = 28

So the number of votes won be A are 28.
