FAQs on Comparison of Fractions Video Lecture - Mathematics for Class 5

1. What are fractions and how are they represented?
Ans. Fractions represent a part of a whole and consist of two numbers: the numerator and the denominator. The numerator indicates how many parts we have, while the denominator shows how many equal parts the whole is divided into. For example, in the fraction ¾, 3 is the numerator and 4 is the denominator.
2. How can we compare fractions with different denominators?
Ans. To compare fractions with different denominators, we can use a common denominator. This means converting both fractions to have the same denominator, making it easier to compare them. Once they share a common denominator, we can compare the numerators to see which fraction is larger or smaller.
3. What is the process of simplifying fractions?
Ans. Simplifying fractions involves reducing them to their simplest form. This is done by dividing both the numerator and the denominator by their greatest common factor (GCF). For instance, to simplify the fraction 8/12, we find that the GCF of 8 and 12 is 4, so we divide both by 4, resulting in 2/3.
4. Can you explain how to add or subtract fractions?
Ans. To add or subtract fractions, we first need a common denominator. If the fractions have the same denominator, we can simply add or subtract the numerators and keep the denominator the same. If they have different denominators, we convert them to a common denominator first, then perform the addition or subtraction on the numerators.
5. Why is it important to understand fractions in everyday life?
Ans. Understanding fractions is essential in everyday life as they are used in various situations, such as cooking, dividing items, measuring distances, and managing finances. Being able to compare, add, and subtract fractions helps us make informed decisions and solve practical problems effectively.
