Key Points

  • A ratio is a relationship in quantity or degree between two things. We use the word ratio when you want to make a comparison between two things. A ratio expresses a proportion.
  • Fractions represent equal parts of a whole or a collection. Fraction of a whole: When we divide a whole into equal parts, each part is a fraction of the whole. 
    • The second statement is true because here the ratio of girls to the total children in the classroom is given as 3/8. This means that if the total number of girls in the class is divided by the total number of children in the class then a ratio of 3:8 will be formed. And also this is a fraction because if the total students in the class are taken as a whole and only girls or selected from that then a fraction of 3/8 is formed.
    • The third statement is also correct because Rimjhim walked 3/4 of a kilometer which means that if a kilometer is taken as a whole in the Rimjhim walked 3 parts out of 4 parts and this is not a ratio because no comparison is being done here.

Additional Information

  • On the other hand, the first statement is wrong because the ratio of boys to girls in a classroom is given where there is a comparison but not taking parts from the whole so it is not a fraction.

Hence b and c are the correct options

Mr.Rohan while helping the students of Class IV in adding and subtracting fractions observed that several students are not able to complete the addition of two improper fractions. He gave a small test with questions from the addition of proper fractions (one item of addition of two similar fractions, three items from the addition of proper and improper fractions, and four items from the addition of improper fractions). He analyzed the responses of each student and found that nearly 45% of students were not clear in adding proper with improper fractions which were affecting their performance in adding two improper fractions. He, therefore, focused on developing the understanding of improper fractions and their addition with proper fractions after which he proceeded to teach the addition of two improper fractions. Which kind of assessment is depicted by this situation?
Given below are three quantities named A, B and C. Based on the given information, determine the relation among the three quantities. Total number of pupils in three classes of a school is 1288. The ratio of children in three classes X, Y, Z is 39 : 64 : 58. In class X number of boys are 26 less than number of girls. Number of boys in class Y is 67.83% more than the number of boys in class X. And, girls in class Z are 25.36% less than the number of girls in class Y. (In calculating number of boys and girls, the decimal value must be rounded off to nearest whole number). Quantity A: Number of boys in class Z. Quantity B: Number of girls in class X. Quantity C: Number of girls in class Y.
