In ten thousands place, 1,83,421 has the greatest number. So, 1,83,421 is greater than 1,73,287 and 1,78,631. The remaining two numbers have 7 in ten-thousands place. But in thousands place 3 < 8. So, 1,73,287 < 1,78,631; %u2022 1,78,631 is greater than 1,73,287.1,32,528 < 1,37,428 < 1,38,640 < 1,73,287 < 1,78,631 < 1,83,421 (ascending order)1,83,421 > 1,78,631 > 1,73,287 > 1,38,640 > 1,37,428 > 1,32,528 (descending order)PredecessorThe number that comes just before a given number is called its predecessor. To find the predecessor of a given number, we subtract 1 from the given number.Examples : Find the predecessors of the following numbers. a. 650 b. 7,900 c. 10,00,000a. Predecessor of 650 = 650 %u2013 1 = 649b. Predecessor of 7,900 = 7,900 %u2013 1 = 7,899c. Predecessor of 10,00,000 %u2013 1 = 9,99,999SUCCESSOR AND PREDECESSOR OF A NUMBERSuccessorThe number that comes just after a given number is called its successor. To find the successor of a given number, we add 1 to the given number.Examples : Find the successors of the following numbers. a. 799 b. 8,595 c.99,999a. Successor of 799 = 799 + 1 = 800b. Successor of 8,595 = 8,595 + 1 = 8,596c. Successor of 99,999 = 99,999 + 1 = 1,00,000Let's Understand Conceptual UnderstandingLet's Understand Conceptual Understanding
