Answer:
2 and 39 over 68
Explanation:
First you find the first common factor which could be the other number
7x17 14 x 4
4x17 14x 4
and that gets you to the smallest number they can be to be even which could be very large like 68
119 over 68 + 56 over 68
but you don't add the 68 or the bottom number so its
119 +56 =175
and 175 over 68 can be simplified to 2 and 39 over 68
