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.
The RD Sharma Solutions for Class 7 Rational Numbers are designed to help you understand each concept clearly and easily. The solutions cover every exercise question from the textbook, with step-by-step explanations. This makes it easier for students to follow along and practice at their own pace. Whether you are solving simple problems like finding the numerator and denominator or working with addition and subtraction of rational numbers, these solutions will guide you through each step.

In this chapter, students will learn about decimals and how to perform basic operations with them. The solutions provided here are detailed and easy to follow, helping students understand each concept thoroughly.
Q1. Write the numerators of these rational numbers:
Q2. Write the denominators of these rational numbers:
JEE
NEET
Foundation JEE
Foundation NEET
CBSE
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:
Positive Rational Numbers: (9/8), (-19/-13)
Q9. Find which numbers are negative:
Negative Rational Numbers: (-3/7), (9/-83)
Rational numbers are numbers that can be written in the form of p/q, where p and q are integers, and q is not zero. These include positive numbers, negative numbers, zero, and fractions.
