Decimals are a method of writing fractional numbers without writing a fraction
having a numerator and denominator.

The fraction 7/10 could be written as the decimal 0.7

The period or decimal point indicates that this is a decimal.

The decimal 0.7 could be pronounced as ** SEVEN TENTHS ** or as ** ZERO POINT SEVEN**.

There are other decimals such as hundredths or thousandths. They all are based on
the number ten just like our number system.

A decimal may be greater than one. The decimal 3.7 would be pronounced as ** THREE AND SEVEN TENTHS**.
