a          b         c
42         3        2
3          42       2
42         2        3
2          42       3
3          2        42
2          3        42
a + b + c =42 + 3 + 2 = 47

We can use the concept of Egyptian Fractions to solve this

6/7    divide  7/6  and take the ceiling of this result  =  2

Take the reciprocal of this  =   1/2

So 

6/7  =  1/2 +  remainder

6/7 - 1/2  =  remainder

12/14 - 7/14  =  

5/14  = remainder

divide 14/5  and take the ceiling of this  = 3

Take the reciprocal of this   =1/3

So

6/7  =  1/2  + 1/3  + remainder

6/7  =  5/6 + remainder

6/7 - 5/6  = remainder

36 / 42  - 35/42  = remainder

1/42  =  remainder

So

6/7  =  1/2  + 1/3  + 1/42
