Answer:
40% OF THE ART CLASS ARE 7TH GRADERS
Explanation:
The percentage of 7th graders in art club can be found by dividing the number of 7th graders in the club (22 members) by the total number of club members (55 members);
(# of 7th graders)/(total club members) = the fraction that are 7th graders.
(22/55) = 0.40 OR 40%
