FAQs on Fractions Video Lecture - Mathematics for Class 4

1. What are fractions and why are they important in mathematics?
Ans.Fractions represent a part of a whole and are written in the form of a numerator (top number) and a denominator (bottom number). They are important because they allow us to describe quantities that are not whole numbers, helping in various real-life situations such as cooking, sharing, and measuring.
2. How do you add and subtract fractions?
Ans.To add or subtract fractions, they must have a common denominator. If they do not, you first find a common denominator, convert the fractions, and then add or subtract the numerators while keeping the common denominator. Finally, simplify the fraction if possible.
3. Can you explain how to multiply and divide fractions?
Ans.To multiply fractions, multiply the numerators together and the denominators together. For division, you multiply by the reciprocal of the second fraction (flip it and then multiply). Simplify the result if necessary.
4. What is the difference between proper, improper, and mixed fractions?
Ans.Proper fractions have a numerator smaller than the denominator (e.g., ¾), improper fractions have a numerator larger than or equal to the denominator (e.g., 5/4), and mixed fractions combine a whole number and a proper fraction (e.g., 1 ¾).
5. How can I convert fractions to decimals and vice versa?
Ans.To convert a fraction to a decimal, divide the numerator by the denominator. To convert a decimal to a fraction, identify the place value of the decimal, write it as a fraction with the appropriate denominator, and simplify if necessary.
