(1) the least common denominator of x/y and 1/3 is 6
(2) x = 1
from 1
y could be 2 or 6.......insuff
from 2
insuff
both 1/6 or 1/2........insuff.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.

both 1/6 or 1/2........insuff.E 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....
