Comparing Decimals

To compare two or more decimals, place the numbers in a vertical column with the decimal points in a straight line with each other. Add zeros to the ends of the decimals so that they all have the same number of decimal places. Then compare the numbers, ignoring the decimal points.

Examples

Example 1

Which is larger, 0.43 or 0.561?
