It is: 8/13 diviced by 3/65 = 40/3 or 13 and 1/3
15/65 = 3/13
3/13
It is: 9/13 divided by 12/13 = 3/4 in its simplest form
1, 3, 5, 13, 15, 39, 65, 195.
15/65 simplfies to 3/13
10 divided by 3/4 = 13 and 1/3
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.
