Answer 1

Step-by-step explanation:

0.001 = 0.001001001…

Let x = 0.001001001…. (1)

Here, 3 digit is repeating so multiply by 1000

1000 × x = 1000 × . 001001001….

1000x = 1.001001001…. (2)

On subtracting equation 1 from equation 2

1000x -x = 1.001001001…. - 0.001001001...

999x = 1

x = 1/999

Hence ,0.001 = 1/999
