So here is how I got the simplest form. It took me two steps.
step 1: 56/2= 28 and then I also did 154/2= 77
so far we have 28/77 which can be further reduced:
step 2: ask yourself what goes into 28 and 77 evenly: the answer is 7. So what you do is:
28/7= 4 and 77/7= 11
your final answer is: 4/11
Hopefully this helped and good luck.
