90 minutes as a Decimal
Understanding how to convert time to decimals is a simple yet important skill. Time is often measured in hours, minutes, and seconds. In some contexts, such as calculations for payroll or project management, it's useful to express time as a decimal. Here, we'll focus on converting 90 minutes into a decimal format. A decimal separates the whole number part from the fraction part using a decimal point. The numbers to the left of the decimal point represent the whole hour, and those to the right represent the fractional part of the hour.
