Definitions:

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.
2. Every fraction with denominator 10 can be written in decimal notation and vice-versa.
3. One block divided into 100 equal parts means each part is ( ) 1
100 (one-hundredth) of
a unit. It can be written as 0.01 in decimal notation.
4. Every fraction with denominator 100 can be written in decimal notation and
vice-versa.
5. In the place value table, as we go from left to the right, the multiplying factor becomes 1 /10 of the previous factor.
The place value table can be further extended from hundredths to 1/10 of hundredths i.e. thousandths (11000 ), which is written as 0.001 in decimal notation.
6. All decimals can also be represented on a number line.
7. Every decimal can be written as a fraction.
8. Any two decimal numbers can be compared among themselves. The comparison can start with the whole part. If the whole parts are equal then the tenth parts can be
compared and so on.
9. Decimals are used in many ways in our lives. For example, in representing units of
money, length and weight.
