NCERT Solutions for Class 10 Maths Chapter 1 Exercise 1.4 are available on the Extramarks website and mobile app for students to review rational numbers and their decimal expansion. Real Numbers is a remarkably useful tool. Three questions make up NCERT Solutions for Class 10 Maths Chapter 1 Exercise 1.4, two of which require lengthy responses while one is simple to answer.

Students are urged to keep in mind a few of the key theorems listed below that were mentioned in this section before moving on to solving the practise questions in the NCERT Solutions for Class 10 Maths Chapter 1 Exercise 1.4:

• If x is a rational number for which the decimal expansion comes to an end, then x can be expressed as p/q, where p and q are coprimes, q’s prime factorization is 2n5m, and n and m are non-negative integers.
• The decimal expansion of “x” comes to an end if x = p/q is a rational number and “q” has a prime factorization of the type 2n5m, where “n” and “m” are non-negative integers.
• The decimal expansion of a rational integer, x = p/q, where ‘p’ and ‘q’ are coprimes, is said to be non-terminating repeating if the prime factorization of ‘q’ cannot be represented as 2n5m (recurring).

The decimal expansion of every rational number is either terminating or non-terminating and recurring, as the students will see.

The student will learn as they go through problems that any real number with a terminating decimal expansion can be written as a rational number with a power of 10 as the denominator.

Through the use of pattern recognition, students can use this activity to answer real-world problems.

Through NCERT Solutions for Class 10 Maths Chapter 1 Exercise 1.4 students can examine rational numbers’ decimal expansion with the aid of real numbers. Essential terms like terminating and non-terminating decimals will be introduced to students. Certain rational numbers have a portion of the decimal that repeatedly repeats itself when we convert them to decimal form. These are referred to as non-terminating decimals, and examples include 0.333 and others. On the other hand, the term is said to be terminating if no component of the decimal is repeated, for instance, pi= 3.1415926.

The three theorems about the characteristics of rational numbers described above serve as the foundation for the NCERT Solutions for Class 10 Chapter 1 Exercise 1.4 in Class 10 Mathematics. The concepts of terminating and non-terminating decimals are used in all of the questions. Students can learn about these theorems in steps by using the examples that are presented in this activity.

NCERT Solutions for Class 10 Maths Chapter 1 Real Numbers Exercise 1.4

Let us first know in detail about Real Numbers.

In Mathematics, a Real Number is a quantity that may be represented by an endless number of decimal expansions. In contrast to the natural numbers 1, 2, 3,… that result from counting, real numbers are used in measurements of continuously varying quantities such as size and time. They are distinguished from imaginary numbers, which use the symbol I or the square root of 1, by the word “real.” A complex number has a real (1) and an imaginary I component, like 1 + i.

The positive and negative integers, as well as the fractions created from them (also known as rational numbers), as well as the irrational numbers, are all real numbers. Contrary to rational numbers, whose decimal expansions always contain a digit or group of digits that repeats itself, such as 1/6 = 0.16666… or 2/7 = 0.285714285714, irrational numbers have decimal expansions that do not repeat themselves. Since there is no regularly repeating group in the decimal produced as 0.42442444244442, it is irrational.

Thus, to know such complex concepts better and to make sure that students retain them until the very end, it is important that they refer to the NCERT Solutions for Class 10 Maths Chapter 1 Exercise 1.4 by Extramarks.

Decimal Expansions of Rational Numbers 

The decimal expansion of a rational number is obtained by dividing the numerator by the denominator of the rational number. Decimal numbers can be of two different types:

• Terminating Decimals
• Non-terminating Decimals

1. Terminating Decimals:

The terminating decimal numbers are those decimal numbers with a limited number of digits following the decimal point. They have a limited number of decimal places. Exact decimal numbers are the name given to these decimal numbers.

1. Non-terminating Decimals:

Non-terminating decimal numbers are those that have an endless number of digits following the decimal point.

1.  Non-Recurring Decimals:

Non-recurring decimal numbers are those with an infinite number of digits after the decimal point and digits that do not repeat after the decimal point at regular intervals.

• Terminating Decimal Expansion of Rational Numbers:

The decimal number terminates after a specific number of digits following the decimal point, according to the terminating decimal expansion.

• Non-terminating Decimal Expansion of Rational Numbers:

Some rational numbers never have a remainder that equals zero after decimal expansion. A non-terminating recurring decimal number is produced by a rational number whose denominator has prime factors other than 2 and 5. In the quotient section, we thus have a block of repeated numerals. The expansion can be described as non-terminating and recurrent.

Terminating and Non-terminating Decimals 

A fraction is a number that, in Mathematics, designates the portion of a whole. The fraction is therefore a ratio of two numbers. In contrast, a decimal is a number that has a decimal point separating the whole number portion from the fractional portion. Decimal numbers can be categorised into a variety of groups, including repeating and non-repeating decimals and terminating and non-terminating decimals. Since we can readily simplify fractional numbers, converting a decimal to a fractional value is preferred when addressing many mathematical issues.

Terminating and Non-terminating Decimals:

A decimal with an end digit is referred to as a terminating decimal. It is a decimal, which means that its digits are limited .

For instance, 0.15, 0.86, etc.

The decimals that lack an end term are known as non-terminating decimals. There are indefinitely many terms in it.

For instance, 0.5444444, 0.1111111, etc.

How to Check whether a given Rational Number is Terminating or not? 

Any rational number can be expressed as either a terminating decimal or a repeating decimal, which is a fraction in lowest terms. Simply divide the numerator by the denominator, as instructed to the students. They have a terminal decimal if they have a residual of 0. Otherwise, the remainders eventually start to repeat, resulting in a repeating decimal.

If and only if a number is divisible by 10, a decimal expansion of that number is “terminating” (i.e., there are only 0s after a specific number of digits; let’s ignore the ambiguity of substituting 0s with an indefinite period of 9).

• rational (i.e., a fraction of two integers) (i.e., a fraction of two integers)
• a product of a power of 2 and a power of 5 makes up the (reduced) denominator.
• This is the ultimate exception and a small portion of the entire realm of numbers.
