Question

What is zero and non zero rational numbers. Give examples​

Answer 1

Answer:

hey mate your answer is:-

.

.

For example, 0/1, 0/-1, 0/2, 0/-2, 0/3, 0/-3, 0/4, 0/-4 and so on …..

Thus, 0 can be written as, where a/b = 0, where a = 0 and b is any

non-zero integer. Hence, 0 is a rational number.

Answer 2

Answer:

• For example, 0/1, 0/-1, 0/2, 0/-2, 0/3, 0/-3, 0/4, 0/-4 and so on …..

• Thus, 0 can be written as, where a/b = 0,

• where a = 0 and b is any non-zero integer.

• Hence, 0 is a rational number.

Step-by-step explanation:

• A rational number is one which can be expressed in the form p/q,

with p, q as integers (and of course q <> 0).

• You can also define a rational number as an ordered pair (p, q);

• however, there are an infinite number of such ordered pairs representing the same rational number,e.g. (1, 2),(5, 10), (-12, -24).

• You can define an equivalence relation, (a, b) === (c, d) if ad = bc.

• Rational numbers can then be defined as equivalence classes under this equivalence relation.
