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
