The total members of the chess club = 85 members
Alonzo received a total votes of 51 from the 85 members
The percentage of the votes received = number of people who voted for Alonzo divided by the total number of the chess club members
Number of people that voted = 51
Total number of people = 85
Percentage = 51 / 85 x 100%
= 0.6 x 100%
= 60%
Therefore, 60% of the chess club members voted for Alonzo
The answer is 60%
