Answer:
90% of the club member voted for Leila
Step-by-step explanation:
Leila ran for president of the chess club and she received 36 votes . The club has a total of 40 members . The percentage of the club member that voted for her can be computed below.
total member of the club = 40
number that voted for her = 36
a% of 40 = 36
a/100 of 40 = 36
40a/100 = 36
cross multiply
40a = 3600
divide both sides by 40
a = 3600/40
a = 90
%
90% of the club member voted for Leila
