The expanded form of a decimal point involves breaking down the decimal number into its individual place values. For example, the decimal point in the number 3.456 represents the tenths place. In expanded form, this number would be written as 3 + 4/10 + 5/100 + 6/1000. Each digit after the decimal point is divided by a power of 10 corresponding to its place value.
2.16 written in expanded form = 2 + 0.1 + 0.06
