The periodicity of 0.729 is

Answer 1

the periodcoty of 0.729

Answer 2

Answer:

The periodicity 0.729 is 0.729.

Step-by-step explanation:

Let x= 0.7292929

Now,

10x- 7.292929                ............. (1)

1000x = 729.29          ............ (2)

Minus equation 1 from 2

(1000-10)x = 729.29- 7.29

990x = 722

x= 722/990 = 361/495= 0.729
