Correct option is D

Given:

Repeating decimal = 0.434343...

Solution:
Let x = $$0.\overline{43}$$​​
Then multiplying both sides by 100 (since 2 digits repeat):

100x = $$43.\overline{43}$$​​

Now subtracting:

​$$100x - x = 43.\overline{43} - 0.\overline{43} \\ \ \\ 99x = 43 \\ \ \\ x = \frac{43}{99}$$​​

​$$0.434343... = \frac{43}{99}$$​​
