GIVEN THAT 

X = 6.19777.....               
            _
X = 6.197            --------------(1)

SO, PERIODICITY = 1
10X = 61.9777.....              ------(2)

FROM (1) & (2)

10X = 61.97777....
-  X =   6.19777....
___________________
9X = 55.78

X = 55.78 / 9
X = 5578 /900
X = 2789 / 450

I.E P / Q = 2789 / 450

IT DEPENDS ON PERIDICITY
IF PERIODICITY IS 1 = 10X, 2=100X,3=1000X....
SO IT DEPEND ON PERIODICITY
Thanks a lot
wellcome

GIVEN ⇒× = 6.19777.....  
_
× = 6.197 --------------(1)
Multiply by 10 on both sides
10X = 61.9777..... ------(2)

Subtract 1 from 2 

⇒10X - X  = 61.97777....-  6.19777....
⇒9X = 55.78
⇒X = 55.78 / 9
⇒X = 5578 /900
⇒X = 2789 / 450
Thus,P/q= 2789 / 450
