Let $$x$$ = 0.363636.... --------------(i)
Multiplying both sides by 100
=> $$100x$$ = 36.363636.... ------------(ii)
Subtracting equation (i) from (ii)
=> $$100x - x$$ = (36.363636....) - (0.363636....)
=> $$99x = 36$$
=> $$x = \frac{36}{99} = \frac{4}{11}$$
So, 0.363636....written in the form p/q is 4/11
