## FAQs on Introduction to Fractions Video Lecture - Mathematics Olympiad Class 7

 1. What is a fraction?
Ans. A fraction is a way of representing a part of a whole. It consists of two numbers separated by a line, where the number above the line is called the numerator and the number below the line is called the denominator.
 2. How do you read a fraction?
Ans. To read a fraction, you say the numerator as an ordinal number and the denominator as a cardinal number. For example, 3/4 is read as "three-fourths" or "three quarters."
 3. How do you find the fraction of a number?
Ans. To find the fraction of a number, you multiply the number by the numerator of the fraction and then divide the product by the denominator. For example, to find 1/4 of 20, you multiply 20 by 1 and then divide the product by 4, resulting in 5.
 4. How do you simplify a fraction?
Ans. To simplify a fraction, you find the greatest common factor (GCF) of the numerator and denominator and divide both numbers by it. This will reduce the fraction to its simplest form. For example, to simplify 6/12, the GCF of 6 and 12 is 6, so dividing both numbers by 6 gives 1/2.
 5. What is an equivalent fraction?
Ans. An equivalent fraction is a fraction that represents the same part of a whole as another fraction, but with different numbers. To find equivalent fractions, you can multiply or divide both the numerator and denominator by the same number. For example, 2/4 is equivalent to 1/2 because both fractions represent half of the whole.
