30 minutes as a Decimal
Converting minutes into decimal form is a common task in various calculations, such as time management or payroll. Here, we focus on understanding how to express a portion of an hour as a decimal. An hour consists of 60 minutes, and when we need to convert minutes to a decimal, we divide the number of minutes by 60. This helps in representing time in a format that is easy to work with in calculations.
