# Learn

## Decimal place values

We use a decimal point to separate units from parts of a whole, such as tenths, hundredths, thousandths, etc.

• 0.1 is a tenth, 1/10, of a unit
• 0.01 is a hundredth, 1/100 of a unit
• 0.001 is a thousandth, 1/1000 of a unit

In 52.13, the value of the digit '1' is one tenth or 1/10, and the value of the digit '3' is three hundredths or 3/100.

The following slides from Sparx review place value in decimals, and illustrate how place value grids can help you convert place values between words and numbers.
