Which of the following fractions is in simplest form? 2/10 3/18 5/65 10/37

The answer is 10/37 because you cannot reduce it anymore

Fractions in the simplest form essentially means that they cannot be simplified any longer. 

5/65 is definitely not in its simplest form since we can divide both the numerator and denominator by their greatest common factor,5, to get a simpler version. 

We can divide 2 and 10 by their greatest common factor 2 to get a simpler version, therefore 2/10 isn't the answer.

3/18 can be simplified further as well. 

The only thing left is 10/37. 10/37 cannot be simplified further, thusly, that is your answer. 

I’m not positive but i think it’s none of your buisness
