Step-by-step explanationTo find the total number of voters in the barangay, we can set up an equation based on the given information. Let's denote the total number of voters as "x." Given that 2 out of 3 voters voted for Mr. Sison, we can represent this as a fraction: 2/3. Mr. Sison received 2685 votes, which is 2/3 of the total votes cast. So, we can write the equation as: x * 2/3 = 2685Now, we can solve for x by multiplying both sides of the equation by 3/2: x = (3/2) * 2685x = 4027.5Since the number of voters must be a whole number, we round up to the nearest whole number: x = 4028
