At one afterschool event, of the students were 8th graders and the rest were 7th graders. Of the students who were in 7th grade, the ratio of boys to girls was 3:5.
What percent of all the students at the afterschool event were boys who are in the 7th grade? Help plz

It would help if you proofread your questions before you posted them.
"? of the students were 8th graders".
5/9 of the students were 8th graders, the rest were 7th graders....the rest of the question is correct...she forgot to put 5/9
To find the percentage of boys who are in the 7th grade, we need to follow these steps:
1. Calculate the total number of students in 7th grade:
Since we know that the ratio of boys to girls in 7th grade is 3:5, let's assume that the number of boys is 3x and the number of girls is 5x, where x is a common ratio factor.
The total number of students in 7th grade would then be 3x (boys) + 5x (girls) = 8x.
2. Calculate the total number of students in the afterschool event:
We are given that some students are in the 8th grade and the rest are in 7th grade. Therefore, the total number of students would be the sum of the number of students in each grade.
Let's assume the number of 8th graders is a and the number of 7th graders is b.
The total number of students in the afterschool event would be a (8th graders) + b (7th graders).
3. Calculate the percentage of boys who are in the 7th grade:
To find the percentage, we need to divide the number of boys in 7th grade (3x) by the total number of students at the event (a + b) and then multiply by 100 to convert it into a percentage.
The calculation would be: (3x / (a + b)) * 100.
However, since we don't have specific numbers for a, b, or x, we cannot determine the exact percentage. We need more information or values to provide a specific answer.
