This is a simple question on numeral representation. Firstly, we need to understand how whole numbers are represented in different numeral systems. A whole number like 254 is already expressed in its decimal form since decimals are based on the base ten system. The number 254 consists of three digits: the hundreds place (2), the tens place (5), and the units place (4). In decimal notation, there is no fractional part for whole numbers, so there is no need for a decimal point unless we want to indicate precision.
254 in decimal form is simply 254. It is a whole number without any fractional part.
The decimal system is a base ten system, which means it uses ten digits from 0 to 9. The number 254 is already in decimal notation as it represents 2 hundreds, 5 tens, and 4 ones. Since it is a whole number, it does not require a decimal point unless you want to denote precision, such as 254.0. In this case, the .0 would indicate no fractional component, but it is not necessary for whole numbers.
