The ratio of lefthanded to righthanded students in the school was 3 to 14. If the total number in both categories was 714, how many righthanded students were in the school

each group of students is 17 (3 left, 14 right)
714/17 = 42
so, there are 3*42 = 126 lefties
and there are 14*42 = 588 righties
