Remember that dividing by a number is the same as multiplying by its reciprocal.
In other words, x divided by y is the same as x times 1/y. You can see this with something simpler, like 6 divided by 2. You get the same thing by multiplying 6 by 1/2.
So, when you divide 9/5 by 12/5, you can rewirte it as 9/5 times 5/12.
In that case, you can cancel the 5s to get 9/12. This reduces down to 3/4.

= (9 / 5) x (5 / 12)
= 9 / 12
= 3 / 4

So easy for sure ^^
9/5 : 12/5 = 9/5 x 5/12
(the one in behind always flipped over)
(then, scratch the five)
= 9/12
= 3/4
you'll get the same answer if you do the 9x5/12x5, but..it's spend too much time to get the 3/4

(9/5)/(12/5) = (9/5)x(5/12) = 45/60 = 3/4

9 12
-- \ ---
5 5
You just flip over the second fraction so
12
----
5
becomes
5
---
12
The \ symbol becomes into X
so..
9/5 x 5/12 = 45/60
In LCD= 3/4

you can ignore the denominators, as they will cancel. 9/12 = 3/4
