We know that 4.2626 lies between 4 and 5.So, divide the gap between 4 and 5 into ten parts.So, we get 4,4.1,4.2,4.3,4.4,4.5,4.6,4.7,4.8,4.9,5Now, if we see closely, we can observe that 4.2626 lies between 4.2 and 4.3.So, divide the gap between 4.2 and 4.3 into ten parts.We get 4.2,4.21,4.22,4.23,4.24,4.25,4.26,4.27,4.28,4.29,4.3Now, if we observe more closely 4.2626 lies between 4.26 and 4.27.Divide the gap between 4.26 and 4.27 into ten parts.So, we get 4.26,4.261,4.262,4.263,4.264,4.265,4.266,4.267,4.268,4.269,4.27.Now, if we see closely, we can observe that 4.2626 lies between 4.262 and 4.263.Divide the gap between 4.262 and 4.263 into ten parts.So, we get 4.262,4.2621,4.2622,4.2623,4.2624,4.2625,4.2626,4.2627,4.2628,4.2629,4.263.Finally, we have spotted 4.2626 on the number line.
