FAQs on Multiplication of Fractions Video Lecture - Class 7

1. What is the rule for multiplying fractions?
Ans. To multiply fractions, you simply multiply the numerators together and the denominators together. The resulting fraction is the product of the two fractions.
2. Can you give an example of multiplying fractions?
Ans. Sure! Let's say we want to multiply 2/3 by 1/4. We multiply the numerators (2 x 1) to get 2 and multiply the denominators (3 x 4) to get 12. So, the product of 2/3 and 1/4 is 2/12, which can be simplified to 1/6.
3. What happens if one or both of the fractions have mixed numbers?
Ans. If one or both of the fractions have mixed numbers, you can convert them to improper fractions before multiplying. Multiply the whole number by the denominator and add the numerator to get the new numerator. Then proceed with multiplying the fractions as usual.
4. Can you explain how to simplify the product of fractions?
Ans. After multiplying the fractions, it is important to simplify the resulting fraction if possible. To simplify, find the greatest common divisor (GCD) of the numerator and the denominator. Divide both the numerator and the denominator by the GCD to get the simplified fraction.
5. Is it possible to multiply a fraction by a whole number?
Ans. Yes, it is possible to multiply a fraction by a whole number. To do this, convert the whole number into a fraction by giving it a denominator of 1. Then, multiply the fractions following the usual multiplication rule. The resulting fraction will have the numerator as the product of the whole number and the original numerator, and the denominator will remain the same.
