7/8 = 0.875.....multiply by 100 to get ur percent = 87.5%
Hey there! Instead of trying to explain, I’ll give you a visual of the way I calculated it.
I attached a photo.
I hope this helps and if you have questions about it, post them in chat! Happy to help.

this is because there are 27 total students and 3 groups. let x represent the number of students per group. the equation would be 3(x)=27
if u need to solve for x, it would be x =9
9r=3r+6
Subtract 3r from both sides
6r=6
Divide both sides by 6
r=1
