Question

1 Zero is the additive identify for
(a) Only integers
(b) only whole numbers
(c) only natural numbers
(d) all rational numbers​

Answer 1

Answer:

(b) only whole number

Whole number , start 0, 1,2,3, 4,5 ,6,7,8,9

Answer 2

Answer:

All rational numbers;Option(d)

Step-by-step explanation:

Zero is the additive identity for all rational numbers because the property of additive identity is nothing but adding a number which gives the number itself

Ex: Option-(a); only integers

● -2+0=-2

Option-(b); only whole numbers

● 2+0=2

Option-(c); only natural numbers

● 4+0=4

Option-(d); all rational numbers

● 2/3+0=2/3

as all the options are having the additive indentity as zero we should consider the 4th option because all the above options are the subsets of option (d) I.e;

Natural C Whole C Integers C Rationals C Real

meaning is that all the numbers first three options comes under rational numbers.

Finally the answer is option(d) I.e all the rational numbers

Hope the answer is clear and helpful
