FAQs on Fraction Video Lecture - Mathematics Olympiad for Class 3

1. How do I add fractions with different denominators?
Ans. To add fractions with different denominators, you need to find a common denominator. This can be done by finding the least common multiple (LCM) of the denominators. Once you have the common denominator, you can add the fractions by adding the numerators and keeping the common denominator. Finally, simplify the fraction if possible.
2. What is the difference between a proper fraction and an improper fraction?
Ans. A proper fraction is a fraction where the numerator is smaller than the denominator. In other words, the value of the fraction is less than 1. On the other hand, an improper fraction is a fraction where the numerator is equal to or greater than the denominator. The value of an improper fraction is equal to or greater than 1.
3. How do I convert a fraction to a decimal?
Ans. To convert a fraction to a decimal, divide the numerator by the denominator. The result will be the decimal equivalent of the fraction. If the division is not exact, you may need to round the decimal to a certain number of decimal places depending on the desired accuracy.
4. Can fractions be negative?
Ans. Yes, fractions can be negative. A negative fraction is indicated by a negative sign in front of the fraction. The negative sign is applied to the numerator or the denominator, but not both. For example, -3/4 is a negative fraction, whereas 3/-4 is also a negative fraction.
5. How do I simplify a fraction?
Ans. To simplify a fraction, find the greatest common divisor (GCD) of the numerator and the denominator. Divide both the numerator and the denominator by their GCD to obtain the simplified fraction. The simplified fraction should have the smallest possible whole numbers as its numerator and denominator.
