## thehumantorch10 one year ago Solve for a. a+1/4-a+2/6+a+3/9=2 a.0 b.7 c.9 d.63 Medal and Fan for answer and explanation

$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=???$

hmmm.. i dont understand the whole lcd thing.

3. LynFran

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"...

ok......

5. thehumantorch10

hmmmm i dont know... the choices are 0,7,9 and 63. i just double-checked

ok what exactly is the sum/problem..check this out https://www.symbolab.com/solver/algebra-calculator/a%2B%5Cfrac%7B1%7D%7B%204%7D-a%2B%5Cfrac%7B2%7D%7B6%7D%2Ba%2B%5Cfrac%7B3%7D%7B9%7D%3D2/?origin=enterkey
