2 hours 15 minutes as a Decimal

Professor Greenline Explaining Math Concepts

This is a simple question on decimal conversion. Firstly, we need to understand the relationship between hours and minutes. An hour is a unit of time that is part of a day. There are 60 minutes in an hour. A decimal is a way to represent a number that is not whole, using a (.) or a decimal point to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.

2 hours 15 minutes as a decimal

Answer

 

2 hours 15 minutes can be expressed as 2.25 in decimal form. This shows that the fractional part, 15 minutes, is converted into the decimal form of an hour.

 

Explanation

 

To convert 2 hours 15 minutes to a decimal, we follow these steps:

 

Step 1: Start with the whole hours, which is 2.

 

Step 2: Convert the minutes into a fraction of an hour. Since there are 60 minutes in an hour, divide 15 by 60.

 

Step 3: 15 divided by 60 is 0.25. Step 4: Add the decimal value of the minutes (0.25) to the whole hours (2). The result is 2.25.

 

Therefore, 2 hours 15 minutes is equal to 2.25 when expressed as a decimal.
