The decimal point should be placed in the correct position based on the power of 10 being multiplied by each digit. For example, in the expanded form of 456.789, the decimal point is placed between the digits 4 and 5, indicating that 4 is being multiplied by 100,000, while 5 is being multiplied by 10,000.

Common misconceptions

To convert this expanded form back to standard form, students need to perform addition and multiplication operations while paying close attention to the placement of the decimal point.

To convert a decimal number to expanded form, multiply each digit of the number by a power of 10, starting with the leftmost digit. For example, the decimal number 123.45 can be converted to expanded form as:
