tirumalai Posted September 2, 2008 Share Posted September 2, 2008 A school administrator will assign each student in a group of n students to one of m classrooms. If 3 m classrooms so that each classroom has the same number of students assigned to it? (1) It is possible to assign each of 3n students to one of m classrooms so that each classroom has the same number of students assigned to it. (2) It is possible to assign each of 13n students to one of m classrooms so that each classroom has the same number of students assigned to it. CAN SOMEONE EXPLAIN PLS.

Shooter Posted September 2, 2008 Share Posted September 2, 2008 (B) In simpler terms it is asking whether n/m is an integer? (1) 3n/m is an integer. '3/m' can be integer and the result multiplied by 'n' to get an integer or 'n/m' can be integer and the result multiplied by '3' to get an integer. (2) 13n/m is an integer '13/m' cannot be integer as 'm' is less that '13'. Hence 'n/m' is an integer. Quote Link to comment Share on other sites More sharing options...
