Answer 1

9514 1404 393

Answer:

(i) 5/12

(ii) 720

(iii) 420

Explanation:

(i) The fraction representing all votes is 12/12. If 7/12 were received by the winner, then the loser received 12/12 -7/12 = 5/12 of the total votes.

The person who lost received 5/12 of the total votes.

__

(ii) The winner won by 7/12 -5/12 = 2/12 = 1/6 of all votes. So, the total number of votes is ...

120 votes = 1/6(total votes)

total votes = 6×120 votes = 720 votes

There were 720 registered voters.

__

(iii) The winner received ...

(7/12)(720 votes) = 420 votes . . . received by the winner
