FAQs on What is a Fraction? Video Lecture - Mathematics (Maths Mela) Class 5 - New NCERT

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 top number that indicates how many parts are being considered, and the denominator, which is the bottom number that 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, meaning that 3 out of 4 equal parts are being represented.
2. How do you simplify a fraction?
Ans. To simplify a fraction, you need to divide both the numerator and the denominator by their greatest common divisor (GCD). For example, to simplify the fraction 8/12, we first find the GCD, which is 4. Then we divide both the numerator (8) and the denominator (12) by 4, resulting in the simplified fraction 2/3.
3. 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 ²⁄₅. An improper fraction, on the other hand, has a numerator that is greater than or equal to its denominator, like ⁵⁄₂ or ⁴⁄₄. Improper fractions can also be expressed as mixed numbers, which combine a whole number and a proper fraction.
4. How do you add or subtract fractions?
Ans. To add or subtract fractions, they must have a common denominator. If the denominators are different, you first find a common denominator, which is usually the least common multiple (LCM) of the two denominators. Once you have a common denominator, you adjust the numerators accordingly and then add or subtract the numerators. For example, to add ¹⁄₂ and ¹⁄₃, the common denominator is 6: we convert the fractions to ³⁄₆ and ²⁄₆, respectively, and then add them to get ⁵⁄₆.
5. What are equivalent fractions?
Ans. Equivalent fractions are different fractions that represent the same value or proportion of a whole. For example, the fractions ¹⁄₂, ²⁄₄, and ³⁄₆ are all equivalent because they all represent the same part of a whole. You can find equivalent fractions by multiplying or dividing the numerator and the denominator of a fraction by the same non-zero number.
