15/65 By cancelling down/reduction. We note, in this case, that both numbers end in '5'. So '5' is a common factor; 5 x 3 = 15 and 5 x 13 = 65 So cancel down/reduce by '5' 15/65 = 3/13 Since both '3' & '13' are prime numbers this will NOT reduce any further. Hence 15/65 in its simplest form is 3/13. NB Any number, however large or small, that ends in '5' or '0' , has '5' as a common factor. Refer to your '5' times multiplication table.
