wolfram steered me wrong...yep, 189.
OpenStudy (stormfire1):
Wait...no it didn't. The LCM is 63
Parth (parthkohli):
Well, basically, you can even eliminate fractions by taking the LCD of the LHS, i.e 7 * 9, but not appropriate according to the question
Parth (parthkohli):
But, we see that 7 * 9 can eliminate which is given, so 63.
Parth (parthkohli):
Yes @stormfire1
