**Q.1. Is zero a rational number? Can you write it in the form p/q, where p and q are integers and q â‰ 0?**

i.e**Q.2. ****Find six rational numbers between 3 and 4.Ans. **We know that there are an infinite number of rational numbers between two rational numbers. We will multiply both the numbers, 3 and 4, with 6+1=7 (or any number greater than 6). Therefore, six rational numbers between 3 and 4 can be:

âˆ´ The numbers in between 21/7 and 28/7 will be rational and will fall between 3 and 4.

**Q.3. ****Find five rational numbers between (3/5) and (4/5).****Ans. **There are infinite rational numbers between (3/5) and (4/5).

To find out 5 rational numbers between (3/5) and (4/5), we will multiply both the numbers, (3/5) and (4/5), with 5+1=6 (or any number greater than 5)**Example:**

Therefore, the numbers in between 18/30 and 24/30 will be rational and will fall between (3/5) and (4/5).

Hence,

are the 5 rational numbers between (3/5) and (4/5).**Q.4. ****State whether the following statements are true or false. Give reasons for your answers.****(i) Every natural number is a whole number.****(ii) Every integer is a whole number. ****(iii) Every rational number is a whole number.****Ans. ****(i) True: **( The collection of all natural numbers and 0 is called whole numbers)**(ii) False: **( Integers such as â€“1, â€“2 are non-whole numbers)**(iii) False: **( Rational number (1/2) is not a whole number)
