both sides divide by 5
so
45/5: 75/5
= 9:15
further, both sides now divide by 3
so
9/3:15/3
= 3:5
there is no common factor betwen 3 and 5 so this is the simplest form you can express that ratio
3:5
[edit] its probably worth pointing out since the common factors were 3 x 5 and the answer was 3:5
this is a COINCIDENCE and the factors will not always be shown in the final ration
