To represent a rational number p/q on the number line, we divide the unit interval between two consecutive integers into q equal parts and move p parts to the right if the number is positive. For 0.532, which is 532/1000, we divide the interval between 0 and 1 into 1000 parts and move 532 parts right from 0. For 1.1$\overline{5}$, which is 1 + 7/45, we divide the interval between 1 and 2 into 45 parts and move 7 parts right from 1.
