amsi.org.auThe set of real numbers consists of both the rational numbers and the irrational numbers. Constructing real numbers We have seen in the module ‘ Constructions ’ that every rational number can be plotted on the number line. For example, to plot . 3 5. we first divide the interval from 0 to 1 into 5 equal subinterval (this requires the ...

www.math.ucdavis.edu(b) Let AˆQ be any subset of the rational numbers with at least two elements. Choose x;y2Awith x6= y. The irrational numbers are dense in R, so there exists z2RnQ such that x<z<y. Let U= (1 ;z) \A; V = (z;1) \A: Then U, V are open sets in the relative topology on A. Moreover, x2U, y2V so U, V are nonempty, and U\V = ;, U[V = A. It
