Approximately 10,000 means The Number Of People Died IS More Than 9,000 And Less Than 11,000 means the number lies between 9000-11,000. And It is Just As ROUND OFF.   * Estimating Round off To the Nearest Tens :- For Example 18 Is Near To 10 Or 20. Answer Is 20. It Means 18 Is Rounded Off To 20. Taking Some Examples:- * 27 = 30 *1464 = 1460   * Estimating Round off To the Nearest Hundred :- For Example 180 Is Near To 100 Or 200. Answer Is 200. It Means 180 Is Rounded Off To 200. Taking Some Examples:- *9636 = 9600 *274 = 300   * Estimatin...

Back To Previous / Homepage   |   About me  | *Comparing Numbers:- Lets See Which Is The Greatest Among These:- * 67, 567, 5678, 12462  * 8401, 8041, 8410 , 1804, 1840 * 1788, 19, 17678 , 2000, 1765 Lets See Which Is The Smallest Among These:- * 1788, 1871, 1887, 178 , 1877 * 377, 15646, 2677, 26 , 765 Now we have to look how we Compared Numbers. Looking Numbers We Have Found that Greatest Numbers has the most Thousands and the Smallest is only in Hundreds Or In Tens. If We have To compare same Numerals Numbers That Is Both In Thousands Like ----- 7866 and 6777  . The Greatest Number is 7866 As The Digit In Thousand Place Is Greater that is 7 In 7866 And 6 In 6777 . But If The Both thousand Placed Number Is Same That Is 7866 and 7688   So Now Move To The Next the HUNDRED Place So bigger One IS 7866 As 8 Is Higher In Hundred Place Compare To 6 In 7688.
