Writing numbers in standard form sometimes means using decimal places. What are decimal numbers? Decimal numbers are a way to represent parts of a whole number. Some decimal numbers include a whole number and a part of a number, like 4.6. Others include only a part of a whole number, like 0.75. The part of a number represented by a decimal will always be a factor of ten. Look at the decimal place value chart.
