FAQs on Class 4 Maths Learning Poster Chapter 5 Fractions

1. What are fractions and how are they represented?
Ans.Fractions represent a part of a whole and are written as two numbers separated by a slash, such as 1/2. The top number is called the numerator, indicating how many parts are being considered, while the bottom number is the denominator, showing the total number of equal parts in the whole.
2. How do you add and subtract fractions?
Ans.To add or subtract fractions, they must have a common denominator. If they do not, find the least common denominator (LCD), convert the fractions, and then add or subtract the numerators. For example, to add 1/4 and 1/2, convert 1/2 to 2/4, then add: 1/4 + 2/4 = 3/4.
3. What is the difference between proper and improper fractions?
Ans.A proper fraction has a numerator smaller than its denominator (e.g., 3/4), while an improper fraction has a numerator that is equal to or greater than its denominator (e.g., 5/4 or 4/4). Improper fractions can be converted into mixed numbers, which consist of a whole number and a proper fraction.
4. How do you multiply and divide fractions?
Ans.To multiply fractions, multiply the numerators together and the denominators together. For example, 1/3 × 2/5 = 2/15. To divide fractions, multiply by the reciprocal of the second fraction. For example, 1/2 ÷ 3/4 = 1/2 × 4/3 = 4/6, which simplifies to 2/3.
5. How can I simplify fractions?
Ans.To simplify a fraction, divide both the numerator and the denominator by their greatest common divisor (GCD). For example, to simplify 8/12, find the GCD, which is 4. Then, divide both 8 and 12 by 4 to get 2/3, the simplified form.
