Answer:
The number of students voted in the election = 510 students
Explanation:
It is given that,
2/15 of the students voted for Omar, 
3/5 voted for scott, we get 3/5 = 9/15 
and the remainder voted for lindsey. 
68 students voted for Omar
To find the total students
68 students voted for Omar and 2/15 of the students voted for Omar, 
Let x be the total students,
2x/15 = 68
x = 510
Total students = 510
