This brief essay explores the limit mean densities of subsets of natural numbers m such that the pair (m, m\b) is either coprime or not coprime. Here m\b = floor(m/b) denotes the operation which can be also characterized as 'truncation of the last digit in base b' or 'right truncation in base b'. The analysis leads to an interesting rational-valued function.
