Answer 2

Answer:

Step-by-step explanation:

Predecessor:

                     A value that comes immediately before, just before, or before a specific value is known as a predecessor.If a value is x (where x can be any whole number), then x-1 will be x's predecessor. Therefore, we must subtract the supplied value from 1 in order to determine the predecessor of any value.

Examples of Predecessor:

   If x = 5, then predecessor of 5 is 5-1 = 4

   If x = 10, then predecessor of 10 is 10-1 = 9

   If x = 20, then predecessor of 20 is 20-1 = 19

   If x = 50, then predecessor of 50 is 50-1 = 49

   If x = 100, then predecessor of 100 is 100-1 = 99

Hence, Any whole number has a predecessor that is one less than the original value.

Solution:

                  The Predecessor of a number is the number obtained by subtracting 1 to it.

                  Clearly, the predecessor of 1000 ( four digit number) is 1000- 1 = 999 ( Three digit number).  

∴ The given statement is False.
