[ Numerical inequalities. Comparing numbers.]

What is greater: ${ }^{10 \ldots 01} / 10 \ldots 01$ (in the numerator of the number there are 1984 zeros, in the denominator - 1985) or ${ }^{10 \ldots 01} / 10 \ldots .01$ (in the numerator - 1985 zeros, in the denominator - 1986).
Let's denote the number in the numerator as $n$. Then the entire fraction is equal to $n / 10n - 9$, and its reciprocal is $10 - 9 / n$. From this, it is clear that the larger $n$ is, the smaller the fraction.

## Answer

The first fraction is greater
