number system is a positional notation with base 10. It is used to refer to
numbers that have a fractional part separated from the integer part with
decimal separator. Decimals help us to write fractional numbers without writing
a fraction with numerator and denominator.
Decimal Place Value Chart
writing any number, the position of each digit is very crucial.
we move to the right in the above place value chart, the value of digit becomes
ten times smaller i.e. one tenth and when we move to the left in the chart, the
value of digit becomes ten times bigger.
One – tenth
can write it as 0.1.
0.1 = 1/10 = One - tenth
One part of 10 equal parts is one – tenth and written as 1/10 or
One – hundredth
can write it as 0.01
0.01 = 1/100 = One - hundredth
One part of 100 equal parts is one – hundredth and written as 1/100
One – thousandth
can write it as 0.001
0.001 = 1/1000 = One - thousandth
One part of 1000 equal parts is one – thousandth and written as
1/1000 or 0.001
So, 0.1, 0.01, 0.001 are decimal numbers.
