FAQs on Fractions - 1 Video Lecture - Mathematics Class 6 ICSE

1. What are fractions and how are they used in everyday life?
Ans. Fractions represent a part of a whole and are expressed as two numbers separated by a slash, for example, 1/2 or 3/4. In everyday life, fractions are used in cooking (like measuring ingredients), in shopping (calculating discounts), and in time management (like splitting an hour into quarters).
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 first find the least common denominator (LCD). Convert the fractions to equivalent fractions with that common denominator, then add or subtract the numerators while keeping the denominator the same. 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 is when the numerator (the top number) is less than the denominator (the bottom number), such as 3/4. An improper fraction is when the numerator is greater than or equal to the denominator, like 5/4 or 4/4. Improper fractions can also be converted into mixed numbers, which combine a whole number and a proper fraction.
4. 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, the GCD of 8 and 12 is 4. So, divide both by 4: 8 ÷ 4 = 2 and 12 ÷ 4 = 3, resulting in the simplified fraction 2/3.
5. What are equivalent fractions and how do I find them?
Ans. Equivalent fractions are different fractions that represent the same value, such as 1/2 and 2/4. To find equivalent fractions, you can multiply or divide the numerator and denominator by the same number. For instance, multiplying 1/3 by 2 gives you 2/6, which is equivalent to 1/3.
