Question

In the fourth grade class at Baker Elementary, 9 students are left-handed. The fifth grade has 7 left-handed students and the sixth grade has 6. The number of students in the fourth grade is 3 times the number of left-handed 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 left-handed students?

Answer 1

4th Grade:
9 Left-handed students.
Total = 3 * 9 = 27 Students.
9/27 = 1/3 Are left-handed.

5th Grade:
7 Left-handed students.
Total = 30-2 = 28 Sudents.
7/28 = 1/4 Are left-handed.

6th Grade:
6 Left-handed students.
Total = 27+3 = 30 Students.
6/30 = 1/5 Are left-handed.

The 4th Grade has the greatest fraction of left-handed students.
