                  Predecessor

                  The number that comes just before the given number is called its predecessor.

                  To find the predecessor of any number, subtract 1 from the number.

                  example 2: Find the predecessor of:

                       (a)  30                          (b)  921                         (c)  8,120

                  Solution:  (a) The predecessor of 30 is 30 – 1 = 29
                                 (b) The predecessor of 921 is 921 – 1 = 920

                                 (c) The predecessor of 8,120 is 8,120 – 1 = 8,119

                           Think and Answer
                         Write 'T' for true and 'F' for false in the given boxes.
                         1.  The greatest 2-digit number is the predecessor of the smallest 3-digit number.
                         2.  The smallest 2-digit number is the successor of the greatest 1-digit number.
                         3.  The smallest 4-digit number is the successor of the smallest 3-digit number.
                         4.  The greatest 3-digit number is the predecessor of the greatest 4-digit number.

                  even Numbers

                  All the numbers that can be made into pairs are called even numbers.

                  Here are 6 oranges, which have been kept in pairs.

                  So, 6 is an even number.
                  All the numbers that have 2, 4, 6, 8 and 0 in the ones place are even numbers.

                  For example: 52, 124, 520, 3008, etc.
                  odd Numbers

                  The numbers that cannot be made into pairs are called odd numbers..
                  Here are 7 oranges; out of them 6 have been kept in pairs and 1 orange is left unpaired.

                  It means 7 cannot be made into pairs.
                  So, 7 is an odd number.

                  All the numbers that have 1, 3, 5, 7 and 9 in the ones place are odd numbers.

                  For example: 29, 343, 695, 82, 71, etc.

                           Think and Answer
                        Is your class roll number even or odd?
