Expanded notation of Decimals

Expanded notation is a way of writing numbers to show the value of each digit. It breaks down a number into its individual place values.

(4 X 10) + (8 X 1) + (2 X 0.01)

(3 X 1) + (4 X 0.1) + (8 X 0.01)

4.38

(4 X 10) + (8 X 1) + (1 X 0.1) + (2 X 0.01)

(2 X 1) + (3 X 0.01)

The digit '4' represents 40, which is 4 times 10.

The digit '8' represents 8, which is 8 times 1.

The digit '2' represents 0.02, which is 2 times 0.01.

Add all the values together. For example, (4 X 10) + (8 X 1) + (2 X 0.01) = 40 + 8 + 0.02 = 48.02.
