Expanded Notation with Decimals

As we convert from denominate numbers to expanded notation, the focus shifts to a different way of expressing place value. Let us see with the help of example how to wrote whole numbers and decimals using place value and expanded notation.

 Whole number Decimal number Place value of decimal Ten thousands thousands hundreds tens ones Decimal point tenths hundredths thousandths Ten thousandths Hundred thousandths Number 4 6 9 2 7 . 0 3 8 9 4

Hence, given number 46927.03894 can be written in expanded notation as follows:

46927.03894 = (4 × 10,000) + (6 × 1000) + (9 × 100) + (2 × 10) + (7 x 1) + (0 × $\frac{1}{10}$) + (3× $\frac{1}{100}$) + (8× $\frac{1}{1000}$) + (9× $\frac{1}{10000}$) + (4× $\frac{1}{100000}$)
