Explanation:

4 (sixth grader) : 7(seventh grader)

7 x 5 is 35

Answer: 35 seventh graders

Explanation:

The simplified ratio is 4:7 sixth graders to seventh graders

The number of sixth-graders is 5 times the number shown in the ratio of attendees (20/4 = 5). Thus, the number of 7th graders must also be 5 times greater than the simplified ratio.

7*5 = 35, thus there are 35 seventh graders in the club
