420 as a decimal

Professor Greenline Explaining Math Concepts

Understanding decimal representation is a fundamental aspect of mathematics. In this context, the number 420 is already a whole number and does not require conversion to a decimal. A decimal is typically used to represent numbers that are not whole, using a decimal point to separate the integer part from the fractional part. In this case, since 420 is a whole number, its decimal representation is simply 420.0.
