CBSE Class 6th ( VI) Mathematics Chapter 7. Fractions: Exercise 7.2 Solutions

  1. Proper Fraction :
    1. A proper fraction is a number representing part of a whole.
    2. In a proper fraction the denominator shows the number of parts into which the whole is divided and the numerator shows the
      number of parts we have taken out.
    3. In a proper fraction the numeratoris always less than the denominator.
    4. On a number line, all these fractions lie to the left of 1as they are less than 1.For Examples
      12357

      ,
      ,
      ,
      ,
      4  6  9  10  12 
      are all proper fractions
  2. Improper Fraction :
    1. The fractions, where the numerator is bigger than the denominator are called
      improper Factions. For Examples
      37121827

      ,
      ,
      ,
      ,
      2  3  7  5  8 
      are all improper fractions
  3. Mixed Fraction :
    1. A mixed fraction has a combination of a whole and a part.For example :
      2312
      5
      , 4
      , 7
      , 3
      3767
      are all mixed fractions
