Answer 1

   9   +  7   +  2  =
   2       4       3
m.m.c
2,4,3........2
1,2,3........2
1,1,3........3
1,1,1.........12

54 + 21 + 8  = 83
       12            12

Answer 2

$\frac{9}{2} + \frac{7}{4} + \frac{2}{3} \to mmc = 12 \\ \\ \frac{9 }{12} + \frac{7}{12} + \frac{2}{12} \\ \\ \frac{54 + 21 + 8}{12} = \boxed{ \frac{83}{12} }$
