FAQs on Let's Learn: Fractions - Mathematics for Class 5: NCERT

1. What is a fraction and how is it represented?
Ans. A fraction is a mathematical expression that represents the division of one quantity by another. It consists of two parts: the numerator (the top number) and the denominator (the bottom number). For example, in the fraction ¾, 3 is the numerator, and 4 is the denominator, indicating that 3 parts of a whole are being considered out of 4 equal parts.
2. How do you add fractions with different denominators?
Ans. To add fractions with different denominators, you first need to find a common denominator. This is typically the least common multiple (LCM) of the denominators. Once you have a common denominator, convert each fraction to an equivalent fraction with this denominator. Then, add the numerators while keeping the denominator the same. For example, to add ⅓ and ¼, the LCM of 3 and 4 is 12. So, convert ⅓ to ⁴⁄₁₂ and ¼ to ³⁄₁₂, then add them to get ⁷⁄₁₂.
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 ⅖. An improper fraction, on the other hand, is where the numerator is greater than or equal to the denominator, like ⁵⁄₄. Improper fractions can also be expressed as mixed numbers, which combine a whole number with a proper fraction, such as 1⅓ for ⁴⁄₃.
4. How do you convert a fraction to a decimal?
Ans. To convert a fraction to a decimal, divide the numerator by the denominator. For example, to convert ¾ to a decimal, you would perform the division 3 ÷ 4, which equals 0.75. This method allows you to express the fraction in decimal form accurately.
5. What are equivalent fractions and how can you find them?
Ans. Equivalent fractions are different fractions that represent the same value or proportion of a whole. To find equivalent fractions, you can multiply or divide the numerator and denominator of a fraction by the same non-zero number. For instance, ½ is equivalent to ²⁄₄ because both represent the same portion of a whole when simplified.
