Answer 2

Answer:

Let us consider a = 0.621621621…

Multiplying LHS and RHS by 1000, we get

1000a = 621.621621621

Splitting up the RHS, we get

1000a = 621 + 0.621621

Since a = 0.621621621, substitute in the above equation,  

1000a = 621 + a

Taking a terms as common, we get

1000a – a = 621

999a = 621

Keeping a on one side, the equation can be simplified as  

The value of a = $\bold{\frac{621}{999}}$
