If the numerator of a fraction is a prime number, can the fraction be simplified? why or why not?

Yes, a fraction with a numerator that is prime can still be simplified.

The definition of a prime number is that it's only two factors are 1 and itself.

If the numerator is prime, it can still be reduced or simplified because it can be divided by itself to get 1.

For example, the number 7 is a prime number. It's only two factors are 7 and 1.

The fraction 7/14 is a fraction where numerator is prime.

7 = 1 because 7 : 7 = 1

14 2 14 : 7 = 2
