the number of right-handed students in a mathematics class is mine times the nimber of left-handed students. the total number of students in the class is 30. how many right-handed students are in the class?
Since there is 1 lefty for every 10 students, wee can easily multiply both sides by 3 to get 3 lefties for 27 right-handeds, and 27/3 is 9. 27 right handed students.
