FAQs on Division of Fractions (Includes: What is reciprocal of a fraction?) Video Lecture - Mathematics (Maths) Class 7

1. What is division of fractions?
Ans. Division of fractions is a mathematical operation that involves dividing one fraction by another. It is done by multiplying the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by interchanging the numerator and the denominator.
2. How do you divide fractions?
Ans. To divide fractions, you need to multiply the first fraction by the reciprocal of the second fraction. For example, to divide 2/3 by 1/4, you would multiply 2/3 by 4/1 (the reciprocal of 1/4). This can be simplified to (2/3) x (4/1) = 8/3.
3. What is the reciprocal of a fraction?
Ans. The reciprocal of a fraction is obtained by interchanging the numerator and the denominator. For example, the reciprocal of 2/3 is 3/2. When you multiply a fraction by its reciprocal, the result is always 1.
4. Can you divide a fraction by a whole number?
Ans. Yes, you can divide a fraction by a whole number. To do this, you can convert the whole number into a fraction by placing it over 1. Then, follow the same process as dividing fractions by multiplying the first fraction by the reciprocal of the second fraction.
5. Can you divide fractions with different denominators?
Ans. Yes, you can divide fractions with different denominators. To do this, you need to find a common denominator for both fractions. Once you have the common denominator, you can convert both fractions into equivalent fractions with the same denominator. Then, proceed with dividing the fractions by multiplying the first fraction by the reciprocal of the second fraction.
