There are 12 boys and 16 girls in a classroom. Witch represents the simplified ratio of girls to student in the classroom?

Step-by-step explanation:

So the givens are, the number of male students and female students, which when summed together gives us the number of total students. 28.

The amount of girls in the class is 16, which is 16/28 of the total class.

Next, to attain the simplified ratio/fraction, we simplify the fraction we got (16/28).

To do this,  we have to find a compatible factor, which is 4 because it is the highest number where both numbers can divide by 4 and attain a whole (non-decimal) number.

(You can look up the process of factoring, but I won't put it here since its common core.)

Now we know that 4*4=16 and 4*7=28, and we can cancel out the additional 4's.

(The common factor.)

Hence, the simplified ratio is, 4/7.
