In the fraction X/Y, where X and Y are positive integers, what is the value of Y?
1) The least common denominator of X/Y and 1/3 is 6
2) X = 1

Pls discuss.

Value of Y can be "2" or "6" for least common denominator of X/Y and 1/3 to be 6.
LCD of 2 and 3 = 6
LCD of 6 and 3 = 6
Hence, (1) = insuff.

(2) - not relevant information. insuff.

Cheers!

In the fraction x/y, where x and y are positive integers, what is the value of y ?

(1) The least common denominator of x/y and 1/3 is 6.
(2) x = 1

In the fraction x/y, where x and y are positive integers, what is the value of y ?

(1) The least common denominator of x/y and 1/3 is 6 --> LCM of y and 3 is is 6 --> y=2 or y=6. Not sufficient.

(2) x = 1 --> no info about y. Not sufficient.

(1)+(2) y can still be 2 or 6. Not sufficient.
