No as 7 is an odd number and 12 is an even.

The answer is true but for completely the wrong reason. If the answer depended on odds and evens then it should not be possible to simplify 3/6 [odd/even].
But as most people who have studied simplification of fractions will know, 3/6 = 1/2.
The reason is that 7 and 12 are coprime. That is to say, they have no factor in common [other than 1].
The fraction 7/12 cannot be reduced any more.
Yes, 12/14 can be reduced to 6/7
It is: 12/14 = 6/7 in reduced terms
7 over 12.
12/42 = 2/7
7 5/6
3/7
17/12 = 1.5833
7/12
7 over 10 can not be reduced!
14 over 24 reduces to 7/12
7 over 80 reduced to in a fraction = 7/80
