Question

Every whole number has its predecessor. True or false? Why?

Answer 1

true
because there is always some number before it and after it
every number is a predecessor to another number 
1 is to 0
2 is to 1

Answer 2

Solution,

• The predecessor of a number is the number that comes just before that number.
• The predecessor of a given number is 1 less than the given number.

• For example, we need to find the predecessor of 100, it means that the predecessor of 100 is (100-1) = 99.
• So, the given statement i.e. every whole number has its predecessor is true.
