FAQs on Fractions Video Lecture - Mathematics Olympiad Class 4

1. What is a fraction?
Ans. A fraction is a number that represents a part of a whole. It consists of a numerator (the top number) representing the part being considered and a denominator (the bottom number) representing the total number of parts that make up the whole.
2. How do you simplify fractions?
Ans. To simplify a fraction, you need to find the greatest common factor (GCF) of the numerator and denominator, then divide both numbers by the GCF to reduce the fraction to its simplest form.
3. What is the difference between a proper fraction and an improper fraction?
Ans. A proper fraction is a fraction where the numerator is less than the denominator, representing a value less than one. An improper fraction, on the other hand, has a numerator that is equal to or greater than the denominator, representing a value equal to or greater than one.
4. How do you add fractions with different denominators?
Ans. To add fractions with different denominators, you first need to find a common denominator by finding the least common multiple (LCM) of the denominators. Then, you can rewrite each fraction with the common denominator and add the numerators together.
5. What is a mixed number?
Ans. A mixed number is a combination of a whole number and a proper fraction. It is written in the form of a whole number followed by a fraction, such as 3 1/4.
