., start overline, 1, 0, end overline

Let x = .101010...

Multiplying both sides of the equation by 100, we get:

100x = 10.101010...

Subtracting the equation x = .101010... from 100x = 10.101010..., we get:

99x = 10

Dividing both sides of the equation by 99, we get:

(99x)/99 = 10/99

Simplifying, we have:

x = 10/99

Therefore, the fraction equivalent to .101010... is 10/99 in simplest form.
