Which of the following ratos is not equalvillent to 4/8. 1/2 9/18 12/32 18/36?

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.

12/32 is not equivalent to 4/8.

4x3=12

8x4=32
