Medal and Fan for answer and explanation

Answer 1

\[a+\frac{ 1 }{ 4 }-a+\frac{ 2 }{ 6 }+a+\frac{ 3 }{ 9 }=2\]\[a-a+a=2-\frac{ 1 }{ 4 }-\frac{ 2 }{ 6 }-\frac{ 3 }{ 9}\]\[a=???\]

Answer 2

hmmm.. i dont understand the whole lcd thing.

Answer 3

ok is that the exact problem that i wrote about? cause im not getting any of ur options ...the LCM is ...ok what are multiples of 4..they are 4, 8, 12...
multiples of 6 are 6, 12,18....
multiples of 9 are, 9,18, 27 ,36... and you look to see what is the lowest common multiple in (4,6 and 9)...example...multiples of 2 and 4
multiple of 2 ...2,4,6,8
multiple of 4....4,8,12,16 etc
the Lowest common Multiple between 2 and 4 is "4"...

Answer 4

ok......
