5th grade math
posted by Stephon on .
In the fourth grade class at Baker Elementary, 9 students are lefthanded. The fifth grade has 7 lefthanded students and the sixth grade has 6. The number of students in the fourth grade is 3 times the number of lefthanded students in the class. The sixth grade has 3 more students than the fourth grade, and the fifth gradehas two fewer students than the sixth grade. Which grade has the greatest fraction of lefthanded students?

4th Grade:
9 Lefthanded students.
Total = 3 * 9 = 27 Students.
9/27 = 1/3 Are lefthanded.
5th Grade:
7 Lefthanded students.
Total = 302 = 28 Sudents.
7/28 = 1/4 Are lefthanded.
6th Grade:
6 Lefthanded students.
Total = 27+3 = 30 Students.
6/30 = 1/5 Are lefthanded.
The 4th Grade has the greatest fraction of lefthanded students. 
Thank you Henry for showing me how to solve the problem!
