(1): X/Y could be 1/2 or 1/6. Insuff.
(2): No info about y. Insuff.

Combined: Still same problem, cannot determine y. Hence, E

1. Least denominator of x/y and 1/3 is 6 => y can be either 2 or 6, insuff -> B,C,E

2. x=1, deno of 1/y and 1/3 is 6 => y can be 2 or 6, insuff, -> C,E

1 & 2, together y can be 2 or 6 => insuff, then E is the answer.

Sorry if my question sounds silly, but how do you calculate LCM for fractions? when i tried to instert 1/2 or 1/6 and 1/3 to an LCM calculator i did not get the result of 6.

L.C.M. of fraction = L.CM of numerator/H.C.F of denominator ......Also note that L.CM * H.C.F =PRODUCT OF NUMBERS...

but in thsi question it was asked only least common denominator and not of whole fraction....2 & 3 L.C.M is 6 ...also 3 & 6 L.C.M is 6....

Also, L.C.M of 1/2 & 1/3 will be 1....As H.C.F of 2 & 3 ..is 1
