Answer: Option B. -> 2 : B The fractions359 and 539 are like fractions, as they have same denominator. To subtract like fractions, we have to subtract only the numerators and keep the denominator same. 539−359=53−359=189=2
Question 34. Determine the numerator and denominator in this fraction: 27
Answer: Option B. -> Numerator = 2; Denominator = 7 : B This is the example of proper fraction. The numberabove the line in a proper/improper fractionis called the numerator and the numberbelow the line is called the denominator. Hence, here the numerator 2 is and the denominator is 7.
Answer: Option A. -> True : A Two equivalent fractions can never have same denominators. And like fractions have same denominators. So, two equivalent fractions can never be like fractions.
Question 37.In a zoo, 45 birds out of 150 are migratory. 35 of the total birds are of the Indian origin. Which kind of birds are greater in number in the zoo?
Answer: Option B. -> Indian birds : B Fraction of migratory birds =45150=310 Fraction of birds of Indian origin =35=610 ...(equivalent fractions) And, we know, 610>310. ∴ The Indian origin birds are greater in number in the zoo.
Answer: Option C. -> 2007 : C 1017 and 997 are like fractions as they have the same denominator. Hence, we can directly add the numerators keeping the denominator as it is. ∴1017+997=101+997=2007
Question 39.State whether True or False - When you divide a whole into parts, the result is a proper fraction.
