Solution:Yes, zero is a rational number it can be written in the form pq.

0 = 01 = 02 = 03 etc. denominator q can also be taken as negative integer.

 

Question 2.Find six rational numbers between 3 and 4.

Solution:Let qi be the rational number between 3

and 4, where j = 1 to 6.

∴ Six rational numbers are as follows:

Thus, the six rational numbers between 3 and 4 are

Question 3.Find five rational numbers between 35 and 45.

Solution:Since, we need to find five rational numbers, therefore, multiply numerator and denominator by 6.
