Answer :

(i)


Now x =


= 0.5454… (i)


Multiplying both sides of equation (i) by 100, we get


100x = 54.5454…. (ii)


Subtracting (i) by (ii), we get


100x – x = 54.5454…. – 0.5454….


99x = 54



(ii)


Now



= 0.621621…. (i)


Multiplying both sides by 1000, we get


1000x = 621.621621…. (ii)


Subtracting (i) by (ii), we get


1000x – x = 621.621621…. – 0.621621….


999x = 621
