4/8 is when simplified equal to 1/2.
So, we look at all the ratios that when simplified isn't equal to 1/2.
1/2 of course is 1/2. Do we exclude that from out possible answers.
9/18 also when simplified is 1/2.
Again, we exclude this from the possible answers.
12/32 when simplified is equal to 3/8. Which is not equal to 1/2. So we can include that in our answer.
18/36 when simplified is again equal to 1/2.
So then answer to this question is 12/32.
