FAQs on Fractions! - Mini Math Movies - Scratch Garden Video Lecture - Mathematics Olympiad for Class 3

1. What are fractions and how are they used in everyday life?
Ans. Fractions represent a part of a whole and are written as one number over another, separated by a line (e.g., 1/2). In everyday life, fractions are used in cooking (e.g., measuring ingredients), in shopping (e.g., discounts), and in time management (e.g., half an hour).
2. How do you add and subtract fractions?
Ans. To add or subtract fractions, they must have a common denominator. If they don’t, you need to find the least common denominator (LCD), convert the fractions, and then add or subtract the numerators while keeping the denominator the same.
3. What is the difference between proper and improper fractions?
Ans. A proper fraction has a numerator that is less than its denominator (e.g., 3/4), while an improper fraction has a numerator that is greater than or equal to its denominator (e.g., 5/4 or 3/3). Proper fractions are less than one, whereas improper fractions are equal to or greater than one.
4. Can fractions be converted into decimals?
Ans. Yes, fractions can be converted into decimals by dividing the numerator by the denominator. For example, 1/2 equals 0.5, and 3/4 equals 0.75. This is often useful for comparing values or performing calculations.
5. How can visual aids help in understanding fractions?
Ans. Visual aids, such as pie charts, fraction bars, or number lines, can help students grasp the concept of fractions more easily. They provide a visual representation of how fractions relate to each other and to whole numbers, making it simpler to understand addition, subtraction, and equivalence of fractions.
