Assuming you want the "09" to repeat indefinitely, here is how you calculate that:Call your number "x", and write the equation:

(Equation 1) x = 1.09090909...

Multiply by 100 (that's two zeros, because it's two digits that repeat):

(Equation 2) 100x = 109.09090909...

Subtract equation (1) from equation (2):

99x = 108

Solve for "x" (as a fraction), and simplify.

Well, darling, 1.0909090909 is the same as 1 and 9/11 in fraction form. It's as simple as that. Math doesn't have to be a headache, honey.
