Question

Mr Taylor has 18 students in his class and 3 of them are left handed. What is the ratio of right handed students to left handed students?

Answer 1

To determine the number of right handed students, subtract the number of left handed students from the total number. 
 
                                            right handed = total - left handed

Substituting the given, 
 
                                             right hand = 18 - 3 = 15

Calculate for the ratio of the right handed to left handed through dividing 15 by 3 which will be further simplified. 
      
                                                 15/ 3 = 5/ 1

Therefore, the ratio of the right handed to left handed students is 5:1
