Answer:

Explanation:
the bar on 6 indicates that 6 is repeated
we require 2 equations with the repeated digit placed after the decimal point.
let x = 0.03666..
multiply both sides by 100 and 1000 to obtain 2 equations.
100x = 3.666.. → (1)
1000x = 36.666.. → (2)
subtract (1) from (2) to eliminate the repeating digits
900x = 33 ( divide both sides by 900 )
x =
=
