FAQs on Fractions - 3 Video Lecture - Mathematics Class 6 ICSE

1. What is a fraction?
Ans. A fraction is a way to represent a part of a whole. It consists of two numbers: the numerator, which is the number above the line, indicating how many parts we have, and the denominator, which is the number below the line, indicating how many equal parts the whole is divided into. For example, in the fraction 3/4, 3 is the numerator and 4 is the denominator.
2. How do you add fractions with different denominators?
Ans. To add fractions with different denominators, first, find a common denominator, which is a number that both denominators can divide into. Then, convert each fraction to an equivalent fraction with this common denominator. Finally, add the numerators together while keeping the common denominator the same. For example, to add 1/2 and 1/3, the common denominator is 6. Convert them to 3/6 and 2/6, then add to get 5/6.
3. What are equivalent fractions?
Ans. Equivalent fractions are different fractions that represent the same value or amount. For example, 1/2, 2/4, and 4/8 are all equivalent fractions because they all represent the same portion of a whole. You can find equivalent fractions by multiplying or dividing the numerator and denominator by the same number.
4. How do you simplify a fraction?
Ans. To simplify a fraction, you divide both the numerator and the denominator by their greatest common divisor (GCD). This reduces the fraction to its simplest form. For example, to simplify 12/16, the GCD of 12 and 16 is 4. Dividing both by 4 gives you 3/4, which is the simplified form.
5. What is the difference between proper and improper fractions?
Ans. A proper fraction is a fraction where the numerator is less than the denominator, such as 3/4. An improper fraction, on the other hand, is one where the numerator is greater than or equal to the denominator, like 5/4 or 4/4. Improper fractions can also be converted into mixed numbers, which consist of a whole number and a proper fraction.
