Answer:

When a number is written in base ten notation it is referred to as a decimal number. The values of the places to the left of the decimal point (or comma in some countries) increase by a factor of ten, from units to tens, hundreds, thousands, tens of thousands, hundreds of thousands, thousands of thousands millions and so on. To the right of the decimal point the values of places decrease by a factor of ten from tenths to hundredth to thousandth etc.

For e.g. 4 032.67 read as four thousand and thirty-two point six seven, is equivalent to
(4 x 1000) + (0 x 100) + (3 x 10) + (2x1)+ (6 x 1/10) + (7 x 1/100).
