Q. In a certain high school, there were 6 students who were not old enough to vote for every 1 student who was old enough to vote. If there were 840 students in the school, how many students were old enough to vote?
Identify Total Parts: There are 6 students not old enough for every 1 who is, so it's like 6+1=7 parts total.
Divide Total Students: Now we divide the total number of students by the total parts, 840÷7.
Calculate Number of Students: Doing the division gives us 840÷7=120.
Calculate Number of Students: Doing the division gives us 840÷7=120.So, there are 120 students old enough to vote, cause that's the 1 part.
