Answer 4

yes, that is correct. You can simplify it by dividing top and bottom by the same number.

notice both are even so you can divide by 2
notice that when you add up their digits (12 ->3 and 450->9) the sum is divisible by 3
that is a trick to know a number can be divided by 3.
so you can divide top and bottom by 2 and by 3 (or 6 = 2*3)

divide top and bottom by 6
