find the largest common denominator
OpenStudy (anonymous):
To simplify or reduce 16/28, first recognize that their greatest common factor is 4. Divide both by 4 for your answer: 4/7.
OpenStudy (austinl):
If you want to be really simplistic, you can just see that they are even numbers, and just divide by 2 until you cannot divide anymore.

8 times
OpenStudy (austinl):
Exactly. \[16\div 2 = 8\div 2 = 4\]
\[28\div 2 = 14\div 2 = 7\]
\[\frac{4}{7}\]
You have to keep the number of divisions equal too.
