# Weyl's Equidistribution Theorem and Measure Theory…

According to Rajendra Bhatia in his book Fourier Series, Weyl's Equidistribution Theorem states that if $x$ is an irrational number, then for every subinterval $[a, b]$ of $(0, 1)$ we have

$lim_{n \rightarrow \infty}$$\frac{1}{N}$$card${$k : 1 \leq k \leq N$, $\tilde{(kx)} \in [a, b]$} = $b - a$ where $\tilde{(kx)}$ is the fractional part of the number $kx$.

My question is what happens if we generalise to measurable subsets of $(0, 1)$?

Does $lim_{n \rightarrow \infty}$$\frac{1}{N}$$card${$k : 1 \leq k \leq N$, $\tilde{(kx)} \in A$} = $\mu(A)$ where $A$ is a measurable subset and $\mu$ the Lebesgue measure function?
