Answer 1

Answer:

A) W is correct answer I think this will help you

Answer 2

Answer:

d) All

Step-by-step explanation:

A set is a group of objects. The elements of the set are the objects that make up the set.

Sets are frequently represented with a capital letter, for S = $\{1, 2, 3, 4\}$.

• W

      Whole Number : $\{0,1,2,...\}$

• N

     Natural Number : $\{0,1,2,3,...\}$

• Z

     Integer number set :   $Z= \{...,-3, -2, -1, 0, 1, 2, 3,...\}$

• A value that, when multiplied by the original number, equals 1, is known as a number's multiplicative inverse. It is a number's reciprocal.

• If x is any number, then 1/x is x's multiplicative inverse. For instance, 1/5 is the multiplicative inverse of 5.

• Since division by zero is not defined, zero does not have a multiplicative inverse because it does not exist or is undefined.
