There are 12 boys and 16 girls in a classroom. what is the simplified ratio of girls to students in the classroom

To start off, we need to make a non-simplified ratio of the number of girls to the total number of students. 
We are given the total number of girls, 16, in the problem, and we need to find the total by adding the number of girls to the number of boys. If there are 12 boys and 16 girls, and 12 + 16 = 28, there is then a total of 28 students in the class. Now, we make our ratio!


Now, all that's left to do is simplify! Both 16 and 28 are divisible by , so divide each number by four and you get:


The answer is 4 girls : 7 students. This means that for every 7 students in the classroom, 4 are girls.

Hope this helps!
