Overview of Rational Numbers Class 7 Maths

  • A rational number is any number which can be represented as the ratio of two integers and where the denominator is not equal to zero.
  • Rational numbers include all whole numbers, fractions, and integers.
  • Rational numbers can be positive, negative, or zero.
  • Examples of rational numbers: 3/4, -2/5, 0, 7, 1/2.

Properties of Rational Numbers

  • Closure Property: The sum, the difference and the product of two rational numbers are also a rational number.
  • Commutative Property: a + b = b + a and a × b = b × a, where a and b are rational numbers.
  • Associative Property: (a + b) + c = a + (b + c) and (a × b) × c = a × (b × c), where a, b, and c are rational numbers.
  • Distributive Property: a × (b + c) = (a × b) + (a × c), where a, b, and c are rational numbers.
  • Identity Property: a + 0 = a and a × 1 = a, where a is a rational number.
  • Inverse Property: Given any rational number a, there is an additive inverse -a, and a multiplicative inverse 1/a, where a + (-a) = 0 and a × (1/a) = 1.

Representation of Rational Numbers on the Number Line

  • Rational numbers can be represented on the number line by identifying the point corresponding to the ratio p/q, where p and q are integers and q ≠ 0.
  • There are infinitely many rational numbers between any two given rational numbers.

Operations with Rational Numbers

  • Addition and Subtraction: To add or subtract rational numbers with different denominators, we need to find the least common denominator (LCD) and then perform the operation.
  • Multiplication: To multiply two rational numbers, we multiply the numerators and then multiply the denominators.
  • Division: To divide one rational number by another, we multiply the first rational number by the reciprocal of the second rational number.

By understanding the properties and operations of rational numbers, students can effectively work with them in various mathematical contexts.
