Answer 2

Answer:

42 and 12

Step-by-step explanation:

consider one part as x and other part as 2x/7

x+ 2x/7 = 54

7x +2x = 54 X7

9x        =    378

 x        =  378/9

 x        = 42

Other part is x X 2/7  = 42 X2/7

                                   = 6X2

                                   =12
