NCERT Solutions Class 9 Maths Chapter 1 Number Systems Exercise 1.4- The notion of the position of real numbers is covered in NCERT Solutions for Class 9 Maths exercise 1.4 which includes both terminating and non-terminating recurring decimal expansions on the number line. In mathematics, rational numbers, irrational numbers, natural numbers, whole numbers, integers, and real numbers are split into numerous groups.
Real numbers are combinations of rational and irrational numbers, as shown in exercise 1.4 Class 9 Maths. A rational number is nothing but a number that can be stated as a fraction in the form p/q where p and q are integers and q≠0. An irrational number is one that cannot be represented as a fraction with an integer numerator and denominator. NCERT Solutions for Class 9 Maths Chapter 1 Exercise 1.4 consists of two questions based on the decimal representation given in a string of numbers. Horizontal lines with evenly spaced integers are called number lines. The concept of numbering is well explained in this exercise Class 9 Maths Chapter 1 exercise 1.4. The following exercises are also presented here along with Class 9 Maths chapter 1 exercise 1.4.

Q1 Visualise 3.765 on the number line, using successive magnification.
Answer:
3.765 can be visualised as in the following steps.
First, we draw a number line and mark points on it after that we will divide the number line between points 3 and 4. And then we will divide the points between 3.7 and 3.8 as the number is between both of them.
Q2 Visualise on the number line, up to 4 decimal places.
Answer:
We can rewrite as
Now, 4.2626 can be visualised as in the following steps.
The concept of representing a decimal number on the number line was the emphasis of the NCERT book Class 9 Maths exercise 1.4. The representation of decimal numbers on the number line is the sole focus of NCERT syllabus exercise 1.4 Class 9 Maths. Decimal numbers are fractional numbers expressed in a particular form that is divided into Recurring Decimal Numbers (Non-Repeating or Terminating Decimals) and Non-Recurring Decimal Numbers (Non-Repeating or Terminating Decimals).

Option (d) Negative – 0 – positive
Reason: Mathematically, 0 is the middle point of a number line and all positive numbers occupy the right side of the zero whereas the left side of zero was occupied by the negative numbers on the number line.
-14/7=-2
It lies on the left side since the left side of zero was occupied by the negative numbers on the number line.
-6 is greater than -13. Since we go towards the left on a number line the magnitude of the number increases but due to its negative sign, -6 is greater than -13.
Yes, 0.054 is a non-recurring decimal number. Since 0.054 is a non Repeating and Terminating number.
On dividing 1 by 2, we get 0.5
Thus the decimal representation of 1/2 is 0.5
Yes, the given statement is true. On the number line, Between any two rational numbers, there are infinitely many rational numbers.
All-natural numbers, whole numbers, integers, rational numbers, and irrational numbers can be represented on the number line, according to NCERT solutions for Class 9 Maths chapter 1 exercise 1.4.
There are two questions in the NCERT solutions for Class 9 Maths chapter 1 exercise 1.4, and the questions are based on the concept of the position of real numbers, both with terminating decimal expansions and non-terminating recurring decimal expansions on the number line.
