What you would do is simplify everything so in b. 2/6 would simplify into 1/3 as well as 3/9 and 4/12 would also simplify into 1/3. in group c. you would only have to simplify 4/6 into 2/3 and group d. 2/8 would be 1/4. now I'm assuming that all the numbers in the group would have to simplify to 1/3 in order to be correct so group b. would be the right answer
