QUESTION

Find the predecessor of each of the following integers.
 0 1 – 1 – 125 1000

ANSWER Verified Verified
Hint: To find the predecessor of the integer, subtract 1 from the given integer. So, first of all write the given integer and then subtract 1 from it to get the predecessor of the given integer. So, use this concept to reach the solution of the given problem.

Complete step-by-step solution -

 0
We know that to find the predecessor of any integer, we need to subtract 1 from the given integer.
\[ \Rightarrow 0 - 1 = - 1\]
So, the predecessor of 0 is – 1.
 1
We know that to find the predecessor of any integer, we need to subtract 1 from the given integer.
\[ \Rightarrow 1 - 1 = 0\]
So, the predecessor of 1 is 0.
  – 1
We know that to find the predecessor of any integer, we need to subtract 1 from the given integer.
\[ \Rightarrow - 1 - 1 = - 2\]
So, the predecessor of – 1 is – 2.
 – 125
We know that to find the predecessor of any integer, we need to subtract 1 from the given integer.
\[ \Rightarrow - 125 - 1 = - 126\]
So, the predecessor of – 125 is – 126.
 1000
We know that to find the predecessor of any integer, we need to subtract 1 from the given integer.
\[ \Rightarrow 1000 - 1 = 999\]
So, the predecessor of 1000 is 999.

Note: Predecessor is also called as before numbers. Sometimes they ask to find the successor of the given integer. Then we simply need to add 1 to find the successor which is also called as after numbers of the given integer.
