FAQs on Overview: Fractions Video Lecture - Mathematics Olympiad Class 7

1. What are the different types of fractions?

Ans. There are three main types of fractions: proper fractions, improper fractions, and mixed numbers. Proper fractions have a numerator smaller than the denominator (e.g., 1/2), improper fractions have a numerator larger than or equal to the denominator (e.g., 5/4), and mixed numbers consist of a whole number combined with a proper fraction (e.g., 1 1/2).

2. How do you add and subtract fractions?

Ans. To add or subtract fractions, you need a common denominator. If the fractions have the same denominator, simply add or subtract the numerators and keep the denominator the same. If they have different denominators, find the least common denominator, convert the fractions, and then add or subtract the numerators.

3. What is the process for multiplying fractions?

Ans. To multiply fractions, multiply the numerators together to get the new numerator and the denominators together to get the new denominator. For example, to multiply 2/3 and 3/4, multiply 2 by 3 to get 6 and 3 by 4 to get 12, resulting in 6/12, which can be simplified to 1/2.

4. How do you divide fractions?

Ans. To divide fractions, you multiply by the reciprocal of the fraction you are dividing by. For example, to divide 2/3 by 4/5, you can rewrite it as 2/3 multiplied by 5/4. Then, multiply the numerators and denominators to get the answer, which will be 10/12, simplified to 5/6.

5. Why are fractions important in everyday life?

Ans. Fractions are important in everyday life because they help us in various situations such as cooking (measuring ingredients), budgeting (dividing expenses), and understanding proportions (like in recipes or maps). They are essential for making calculations that involve parts of a whole in many practical applications.
