FAQs on Poster: Fractions - Mathematics Olympiad Class 4

1. What are fractions and how are they used in everyday life?
Ans.Fractions represent a part of a whole and are used in many everyday situations, such as cooking, budgeting, measuring distances, and dividing things among people. For example, if a recipe calls for 1/2 cup of sugar, it indicates that only half of a cup is needed.
2. How do you add and subtract fractions?
Ans.To add or subtract fractions, they must have a common denominator. If they don’t, find the least common denominator (LCD), convert the fractions, and then add or subtract the numerators while keeping the common denominator. For instance, to add 1/4 and 1/3, convert them to 3/12 and 4/12, respectively, and then add to get 7/12.
3. What is the difference between proper and improper fractions?
Ans.Proper fractions have a numerator that is smaller than the denominator (e.g., 3/4), while improper fractions have a numerator that is equal to or larger than the denominator (e.g., 5/4 or 3/3). Improper fractions can be converted to mixed numbers, which combine a whole number and a proper fraction.
4. 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, to convert 3/4 to a decimal, divide 3 by 4, which equals 0.75. This method helps in comparing fractions and understanding their values in a different format.
5. What are equivalent fractions and how can you 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 both the numerator and 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.
