Answers

Answer 1

Answer: nromally ratios are in 1:3 format
so I'm guessing that ratio fo winner:total=0.65:1

perople who voted for the winner was 0.65 of all the voters
so find 0.65 of 80
'of' can be translated to as mutliply
0.65 times 80=52

52 voters voted for the winnner

If you want it in that format and simplified, this is it. y=-x+3
