Q:

There are 12 boys and 16 girls in a classroom. Which represents the simplified ratio of girls to students in the classroom?3 to 44 to 34 to 77 to 4

Accepted Solution

A:
 12 boys                       3 boys
------------- reduces to ------------ 
16 girls                         4 girls

We want the simplified ratio of girls to students.  There are 12+16, or 28, students to start with.  We must reduce 16/28, which is the ratio of girls to students before simplification.  This reduces to 4/7 (4 to 7).
