In the decimal numbering system, each digit of the integer or decimal part occupies a position or order with the following names:
|Tenths||Hundredths||Thousandths||Tenth thousandths||Hundredths thousandths||Millionths|
As for reading, we read the whole part followed by the decimal part, accompanied by the words:
tenths: when there is one decimal place;
hundredths: when there are two decimal places;
thousandths: when there are three decimal places;
tenth thousandths: when there are four decimal places;
hundredths thousandths: when there are five decimal places and so on.
1,2: one integer and two tenths;
2.34: two integers thirty four hundredths
When the integer part of the decimal number is zero, we read only the decimal part.
0.1: one tenth;
0.79: seventy nine hundredths
1. There are other ways to read a decimal number. See reading number 5.53:
- five integers and fifty three hundredths;
- five hundred and fifty-three hundredths;
- five integers, five tenths and three hundredths.
2. Any natural number may be written in decimal form by placing the comma after the last digit and adding zero (s). Examples:
4 = 4,0 = 4,00 75 = 75,0 = 75,00Next: Transforming Decimal Numbers into Decimal Fractions and Vice Versa
