Questions and Answers for CBSE Class 7 Mathematics Chapter "Fractions and Decimals"
- Q1: How do you compare two fractions to find out which is greater?
ANS: You can compare fractions by finding a common denominator and then comparing the numerators, or by converting them to decimals. - Q2: What is the process of adding and subtracting fractions with unlike denominators?
ANS: To add or subtract fractions with unlike denominators, first find the least common denominator (LCD), convert each fraction to an equivalent fraction with the LCD, and then perform the operation. - Q3: How do you multiply a fraction by a whole number?
ANS: To multiply a fraction by a whole number, multiply the numerator by the whole number while keeping the denominator the same. - Q4: What is the easiest method to divide decimals?
ANS: The easiest method to divide decimals is to make the divisor a whole number by multiplying both the divisor and dividend by 10, 100, etc., and then divide as with whole numbers. - Q5: Can you explain how to convert a mixed number into an improper fraction?
ANS: To convert a mixed number into an improper fraction, multiply the whole number part by the denominator, add the numerator, and place the result over the original denominator. - Q6: Why are decimals important to learn?
ANS: Decimals are important because they are used in various aspects of daily life, such as in money calculations, measurements, and scientific data. - Q7: How do you round off decimals to a specific place value?
ANS: To round off decimals, look at the digit right after the place value to which you’re rounding; if it’s 5 or more, round up, if less, round down. - Q8: What is a real-life situation where you would need to subtract decimals?
ANS: A real-life situation for subtracting decimals could be when you’re calculating change due in a financial transaction. - Q9: How do decimals and fractions relate to percentages?
ANS: Decimals and fractions can both be converted to percentages by multiplying by 100, which represents the concept of ‘per hundred.’ - Q10: What strategies can help with understanding fractions and decimals better?
ANS: Visual aids like number lines or pie charts, practice with real-life examples, and step-by-step problem-solving can help with understanding fractions and decimals better.
