FAQs on Ex-5.3, Operations On Rational Numbers, Class 7, Math RD Sharma Solutions - RD Sharma Solutions for Class 7 Mathematics

1. What are rational numbers?
Ans. Rational numbers are the numbers that can be written in the form of p/q, where p and q are integers and q is not equal to zero.
2. How do we perform addition and subtraction of rational numbers?
Ans. To add or subtract rational numbers, we need to find a common denominator for the given numbers. Then, we add or subtract the numerators while keeping the common denominator unchanged.
3. Can we multiply and divide rational numbers?
Ans. Yes, we can multiply and divide rational numbers. To multiply rational numbers, we multiply the numerators and denominators separately. To divide rational numbers, we multiply the first number by the reciprocal of the second number.
4. How do we simplify rational numbers to their lowest form?
Ans. To simplify a rational number to its lowest form, we divide both the numerator and denominator by their greatest common divisor (GCD). This will give us the simplified or reduced form of the rational number.
5. Can we compare rational numbers?
Ans. Yes, we can compare rational numbers. To compare two rational numbers, we can either convert them to the same denominator and then compare their numerators, or we can cross-multiply and compare the products.
