Answer:

I'm getting -43/12

Step-by-step explanation:

13/3 + 56/9 + 131/18

Taking LCM of first 2 no.s,

   (13 × 3) + 56          131

=  -------------------   +  ------

            9                    18

   39 + 56         131

= --------------   + -------

        9                18

   95     131

= ------ + -----

    9       18

Now, taking the LCM,

  (95 × 2) + 131          321

= ------------------      = ---------

          18                     18

= 321 / 18           → 1

125/6 + 7/12

Taking LCM,

(125 × 2) + 7      257

----------------- =  -------

      12                 12

= 257/12     → 2

Subtracting eqn. 1 and 2, we get:

321       257

-----  -  -------  

18          12

LCM is 36,

∴   321 × 2 - 257 × 3          642 - 771

  -----------------------------  =  ----------------

               36                              36

     -129         -43

= -----------  = --------

      36            12
