Answer 1

Your Question:

Which of the following is not a rational number.

a) -4/7

b) 3

c) 2/0

d) 0/2

Solution:

First, we will describe what is a rational number.

Rational Number:

A number that can be written in the form of p/q

where p and q are co - prime integers and q≠0

But option "c" does not satisfy this rule.

Here q=0

Hence, it is not a rational number.

Answer 2

$\huge\bf\red{Question}$

Which of the following is not a rational number?

1. -4/7
2. 3
3. 2/0
4. 0/2

$\huge\bf\red{Answer}$

$0/2=undefined$

RATIONAL NUMBER

we know that the rational number is always written in the form of p/q

so,

0/2

where p=0(not satisfied)

q=2

so 0/2 is a irrational number.
