Answer:
120/99 is the answer.
Step-by-step explanation:
It has a line over it means that after the point there are infinite numbers of 21.
•Multiply 1.212121... with 100
we get 121.212121...
•Subtract it with the original one
121.212121.. - 1.212121... = 120.000.. = 120
Write it as an equation :-
Let the fraction be x.
(100×x) - x = 120
100x-x = 120
or, 99x = 120
so, x = 120/99
Find conversion between meters and kilometers and then calculate that.
