I am a fraction that isn't improper. Both my Numerator and Denominator are prime numbers such that if they were multiplied together and then had 16 subtracted from the answer, it would equal 19. What are my numerator and denominator?

Open Calculator


5/7. 5 and 7 are both prime and if you multiply them together you get 35. If you do 35-16 you get 19.
