Question

3/13 +31/26 + 85/39 - 8

Answer 1

Answer:

$\frac{-343}{78}$

Step-by-step explanation:

$\frac{3}{13} + \frac{31}{26} + \frac{85}{39}$

The L.C.M is 78

$\frac{18+93+170}{78}$ = $\frac{281}{78}$

Now,

$\frac{281}{78}$ - 8 = $\frac{-343}{78}$

Answer 2

STEP 1

WE WILL TAKEOUT THE LCM OF 13, 26 & 39.

STEP 2

LCM = 78

3/13 × 6/6 = 18/78

31/26 × 3/3 = 93/78

85/39 × 2/2 = 170/78

STEP 3

SOLUTION:

18/78 + 93/78 + 170/78 - 8

18+93+170/78 - 8

281/78 - 8

281/78 -8/1

281/624
