FAQs on Class 7 Maths Chapter 8 Question Answers - Working with Fractions

1. What are fractions, and how are they used in everyday life?
Ans. Fractions represent a part of a whole and are expressed as a ratio of two numbers, with the top number (numerator) indicating how many parts are taken, and the bottom number (denominator) showing how many equal parts the whole is divided into. In everyday life, fractions are used in cooking (like measuring ingredients), in finance (like calculating discounts), and in various practical situations where parts of a whole are involved.
2. How do you add and subtract fractions with different denominators?
Ans. To add or subtract fractions with different denominators, first, you need to find a common denominator. This is a number that both denominators can divide into. Once you have the common denominator, convert each fraction to an equivalent fraction with this denominator. Then, you can add or subtract the numerators and keep the common denominator. Finally, simplify the result if possible.
3. What is the process for multiplying fractions?
Ans. To multiply fractions, simply multiply the numerators together to get the new numerator and multiply the denominators together to get the new denominator. After multiplying, you may need to simplify the fraction by finding the greatest common factor between the numerator and denominator and dividing both by this number.
4. How can I convert a mixed number into an improper fraction?
Ans. To convert a mixed number (which has a whole number and a fraction) into an improper fraction, multiply the whole number by the denominator of the fraction, then add the numerator. The result becomes the new numerator, while the denominator remains the same. For example, for the mixed number 2 1/3, you multiply 2 (the whole number) by 3 (the denominator) to get 6, then add 1 to get 7. Thus, 2 1/3 = 7/3.
5. What are some common mistakes to avoid when working with fractions?
Ans. Common mistakes when working with fractions include forgetting to find a common denominator when adding or subtracting, incorrectly multiplying or dividing the numerators and denominators, and failing to simplify the final answer. It's also easy to misread fractions or mix up the numerator and denominator, so careful attention is essential.
