Answer: 35 seventh graders

Step-by-step 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

Answer:

35

Step-by-step explanation:

4 (sixth grader) : 7(seventh grader)

what do we multiply by 4 to get 20? 5

so we have to do the same to the other part of the ratio

soooo

7 x 5 is 35

finally ur answer is 35

or 20:35
