CBSE Class 6th ( VI) Mathematics Chapter 8. Decimals: Exercise 8.6 Solved

Things to remember...

  1. To understand the parts of one whole (i.e. a unit) we represent a unit by a block. One block divided into 10 equal parts means each part is 1/10 (one-tenth) of a unit. It can be written as 0.1 in decimal notation. The dot represents the decimal point and it comes between the units place and the tenths place.

CBSE Class 10th Science | Chapter 4. Carbon and its Compounds | Solved Exercises

Points to Remember - What you have learnt

  1. Carbon is a versatile element that forms the basis for all living organisms and many
    of the things we use.
  2. This large variety of compounds is formed by carbon because of its tetravalency
    and the property of catenation that it exhibits.
  3. Covalent bonds are formed by the sharing of electrons between two atoms so that
    both can achieve a completely filled outermost shell.
