Sol 1.) Yes, 0 is a rational number. It can be written in the form of p/q where p and q are integers is not equal to 0; like 0/1 here 0/1 is in the form of p/q, 0 is in p and 1 is in q, and q is not equal to 0.

____×_____

Sol 2.) 3 and 4

3/1 × 7/7 = 21/7 and 4/1×7/7 = 28/7
Therefore, the six rational no.s are as follows:-
22/7 , 23/7 , 24/7 , 25/7 , 26/7 ,and 27/7
____×_____

Sol 3.) 3/5 and 4/5

Multiplying both (numerators and denominators)
3/5 × 7/7 = 21/35 and 4/5 × 7/7 = 28/35
Therefore, the five rational no.s are as follows :-
22/35 , 23/35 , 24/35 , 25/35 ,and 26/35
____×_____

Sol 4.) (i) True, since the collection of whole numbers contains all the natural numbers.

(ii) False, for example; -2 is not a whole number.

(iii) False, for example; 1/2 is a rational number but not a whole number.

answer for ex 1.1​

Answer 1

Answer:

I do know this number ok but I'm still solving

Answer 2

Answer:

We know that, rational number is a number which can be written in the form of qp, where q is not equal to zero. Thus, yes, zero is a rational number, as it can be written in the form of qp.

Because you can't divide by zero. In sufficiently well-behaved algebras (this is certainly true of the rational numbers, but it's more generally true) 0 is an additive identity, so 0 + q = q for all q, and multiplication distributes over addition. and p. 0 must be the additive identity.
