Mathematics is a subject that helps us understand the world around us. It teaches us how to think clearly, solve problems, and make smart decisions. In Class 7, one of the most important topics you will learn is Rational Numbers. This topic is part of Chapter 4 in the RD Sharma textbook. It introduces you to a special group of numbers that go beyond just whole numbers and fractions.

Rational numbers are numbers that can be written in the form of a fraction, where the top number (numerator) and the bottom number (denominator) are both integers, and the denominator is not zero. For example, 3/4, -5/2, and 7 are all rational numbers. These numbers can be positive, negative, or even zero. Learning about rational numbers helps you understand how to work with numbers that are not whole, which is very important in real life.

Q1. Write the numerators of these rational numbers:

  • (-7/5) → Numerator: -7
  • (14/-4) → Numerator: 14
  • (-17/-21) → Numerator: -17
  • (8/9) → Numerator: 8
  • 5 → Numerator: 5

Q2. Write the denominators of these rational numbers:

  • (-4/5) → Denominator: 5
  • (11/-34) → Denominator: -34
  • (-15/-82) → Denominator: -82
  • 15 → Denominator: 1
  • 0 → Denominator: any non-zero number

Q3. Find the rational number with:

Numerator = (-3) × 4 = -12

Denominator = (34 - 23) × (7 - 4) = 11 × 3 = 33

So, the rational number is: -12/33

Q4. Convert these rational numbers into integers:

(7/1), (-12/1), (34/1), (-73/1), (95/1) → Integers are: 7, -12, 34, -73, 95

Q5. Write these integers as rational numbers:

-15 → -15/1
17 → 17/1
85 → 85/1
-100 → -100/1

Q6. Find a rational number with:

Smallest 3-digit number = 100

Largest 4-digit number = 9999

So, the rational number is: 100/9999

Q7. Separate positive and negative rational numbers from this list:

List: (-5/-7), (12/-5), (7/4), (13/-9), 0, (-18/-7), (-95/116), (-1/-9)

Positive: (-5/-7), (-18/-7), (7/4), (-1/-9)
Negative: (12/-5), (13/-9), (-95/116)

Q8. Find which numbers are positive:

  • (-8/7) → Negative
  • (9/8) → Positive
  • (-19/-13) → Positive
  • (-21/13) → Negative

Positive Rational Numbers: (9/8), (-19/-13)

Q9. Find which numbers are negative:

  • (-3/7) → Negative
  • (-5/-8) → Positive
  • (9/-83) → Negative
  • (-115/-197) → Positive

Negative Rational Numbers: (-3/7), (9/-83)
