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
