A decimal is a number that has a whole part and a fractional part, separated by a decimal point. For example, 3.14 is a decimal.

To compare two decimals, look at the digits from left to right. The first place where the digits differ determines which decimal is greater.

The symbol '>' means 'greater than'. For example, 5 > 3 means 5 is greater than 3.

The symbol '<' means 'less than'. For example, 2 < 4 means 2 is less than 4.

The symbol '=' means 'equal to'. For example, 0.5 = 0.50 means both values are equal.

To order decimals from least to greatest, compare the whole numbers first, then the decimal parts, starting from the left.

The least number is 28.103.
