We know that 3.765 lies between 3 and 4. So, divide the portion between 3 and 4 into 10 equal parts and look at the portion between 3.7 and 3.8 through a magnifying glass. Then, 3.765 lies between 3.7 and 3.8 Fig. Now, we imagine dividing this again into 10 equal parts. The first mark will represent 3.71, the next 3.72, and so on. To see this clearly, we magnify this as shown in Fig. Then, 3.765 lies between 3.76 and 3.77 Fig. So, let us focus on this portion of the number line Fig and imagine to divide it again into 10 equal pans Fig. Here, we can visualize the 3.761 is the first mark, 3.762 is the second mark, and so on.
