FAQs on Fractions Video Lecture - Mental Maths - Class 1

1. What are fractions and how are they used in everyday life?
Ans. Fractions are numerical expressions that represent a part of a whole. They consist of a numerator (the top number) and a denominator (the bottom number). In everyday life, fractions are used in various situations such as cooking (measuring ingredients), budgeting (dividing expenses), and in construction (calculating dimensions).
2. How do you add and subtract fractions?
Ans. To add or subtract fractions, they must have a common denominator. If they do, simply add or subtract the numerators and keep the denominator the same. If they don’t have a common denominator, find it by determining the least common multiple (LCM) of the denominators, convert the fractions, and then perform the addition or subtraction.
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 6/6). Improper fractions can also be converted to mixed numbers, which consist of a whole number and a proper fraction (e.g., 5/4 becomes 1 1/4).
4. How do you multiply and divide fractions?
Ans. To multiply fractions, multiply the numerators together and the denominators together (e.g., 2/3 × 4/5 = 8/15). To divide fractions, multiply by the reciprocal of the second fraction (e.g., 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12, which simplifies to 5/6).
5. What are equivalent fractions and how can you find them?
Ans. Equivalent fractions are different fractions that represent the same value (e.g., 1/2 and 2/4). To find equivalent fractions, you can multiply or divide both the numerator and the denominator of a fraction by the same non-zero number. For example, multiplying 1/3 by 2 gives you 2/6, which is equivalent to 1/3.
