FAQs on Fractions Video Lecture - Mathematics for Grade 4

1. What is a fraction?
Ans. A fraction is a numerical quantity that represents a part of a whole. It consists of a numerator (the top number) and a denominator (the bottom number).
2. How do you add fractions with like denominators?
Ans. To add fractions with like denominators, simply add the numerators together while keeping the denominator the same. For example, 1/4 + 2/4 = 3/4.
3. How do you subtract fractions with unlike denominators?
Ans. To subtract fractions with unlike denominators, you first need to find a common denominator. Once you have a common denominator, you can subtract the numerators and keep the denominator the same. For example, 1/3 - 1/4 = 4/12 - 3/12 = 1/12.
4. How do you simplify fractions?
Ans. To simplify a fraction, find the greatest common factor (GCF) of the numerator and denominator, then divide both numbers by the GCF. For example, to simplify 4/8, the GCF is 4, so 4/8 simplifies to 1/2.
5. How do you convert a fraction to a decimal?
Ans. To convert a fraction to a decimal, divide the numerator by the denominator. For example, 3/4 is equal to 3 divided by 4, which is 0.75.
