BSEB Bihar Board Class 9th Maths Solutions Chapter 1 Number Systems Ex 1.1

Question 1.
Is zerc a rational number? Can you write it in P the form 𝑝𝑞, where p and q are integers and q ≠ 0?
Solution:
Yes,-zero is a rational number.
Zero can be written in any of the following forms :
01, 0−1, 02, 0−2 and so on.
Thus, 0 can be written as 𝑝𝑞, where p = 0 and q is any non-zero integer.
Hence, 0 is a rational number.

Question 2.
Find six rational numbers between 3 and 4.
Solution:
We know that between two rational numbers x and y, such that x < y, there is a rational number 𝑥+𝑦2. That is, x < 𝑥+𝑦2 < y
A rational number between 12 and 4 is 12(3 + 4) i.e., 72
∴ 3 < 72 < 4
Now, a rational number between 3 and 72 is

Hence, six rational numbers between 3 and 4 are :
258, 134, 72, 154, 318 and 6316

Alternative Method
Since we want 6 rational numbers between 3 and 4, so we write 3 = 3×71×7 = 217 and 4 = 4×71×7 =
We know that 21 < 22 < 23 < 24 < 25 < 26 < 27 < 28
⇒ 217 < 227 < 237 < 247 < 257 < 267 < 277 < 287.
Hence, six rational numbers between 3 = 217 and 4 = 287 are 227, 237, 247, 257, 267 and 277.

Question 3.
Find five rational numbers between 35 and 45.
Solution:
Since we want 5 rational numbers between 35 and 45, so we write
35 = 3×65×6 = 1830
45 = 4×65×6 = 2430
We know that 18 < 19 < 20 < 21 < 22 < 23 < 24
⇒ 1830 < 1930 < 2030 < 2130 < 2230 < 2330 < 2430
Hence, 5 rational numbers between 35 = 45 = 2430 are : 1930, 2030, 2130, 2230, 2330 and 2430.

Question 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.
Solution:
(i) True : Every natural number lies in the collection of whole numbers.
(ii) False – 3 is not a whole number.
(iii) False : 35 is not a whole number.
