Standard, Expanded, and Unit Form of Numbers

Standard Form

The standard form of a number is the regular way we usually write numbers, such as 95.7 or 9.057. It does not show the place value of each digit in the number.

Expanded Form

Expanded form shows the value of each digit in a number. For example, the expanded form of 95.7 could be written as 90 + 5 + 0.7 or 9 tens + 5 ones + 7 tenths.

Unit Form

Unit form represents a number in terms of its place value units. For the number 9.057, the unit form could be written as 9 ones + 0.5 tens + 0.07 tenths.

Examples:

  • 95.7 in standard form is 9 tens and 5 ones 7 tenths.
  • 9.10 in expanded form is 9 ones and 10 hundredths.
  • 541.701 in unit form is 5 hundreds 4 tens 1 ones 7 tenths 1 hundredths.

Can you give an example of converting a number from standard form to expanded form?

To convert a number from standard form to expanded form, you can break down the value of each digit in the number. For instance, for the number 9.057, you would write it as 9 ones + 5 tenths + 7 thousandths in expanded form.
