Question 691801: Hi,
Thank you for helping me, as I can not learn under my algebra 2 teacher.
Please simplify the complex fraction:
2/x + 3/xy
----------
3/x^2 + 1/5
Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! The LCD of the fractions 2/x, 3/xy, 3/x^2 and 1/5 is 5x^2y
Multiply this LCD with EVERY fraction listed above
(2/x)*(5x^2y) = 10x^2y/x = 10xy
(3/xy)*(5x^2y) = 15x^2y/xy = 15x
(3/x^2)*(5x^2y) = 15x^2y/x^2 = 15y
(1/5)*(5x^2y) = 5x^2y/5 = x^2y
-------------------------------------------------------
So after all that above, we go from this ugly expression
2/x + 3/xy
----------
3/x^2 + 1/5
to this nicer looking expression
10xy + 15x
-----------
15y + x^2y
and that's as simple as it gets because you can't cancel out any more terms.
