Find The Ratio Of The Following:(a) 30 Minutes To 1.5 Hours
=====================================================
Introduction
In mathematics, ratios are used to compare the size or amount of two or more numbers. When dealing with time, it's essential to understand how to convert between different units, such as minutes and hours. In this article, we will explore how to find the ratio of 30 minutes to 1.5 hours.
Understanding Time Conversion
Before we dive into finding the ratio, let's understand how to convert between minutes and hours. There are 60 minutes in 1 hour. To convert minutes to hours, we can divide the number of minutes by 60. Conversely, to convert hours to minutes, we can multiply the number of hours by 60.
Converting 30 Minutes to Hours
Using Division
To convert 30 minutes to hours, we can divide 30 by 60.
30 / 60 = 0.5
So, 30 minutes is equal to 0.5 hours.
Converting 1.5 Hours to Minutes
Using Multiplication
To convert 1.5 hours to minutes, we can multiply 1.5 by 60.
1.5 * 60 = 90
So, 1.5 hours is equal to 90 minutes.
Finding the Ratio
Now that we have converted both 30 minutes and 1.5 hours to a common unit, we can find the ratio. The ratio of 30 minutes to 1.5 hours is equal to the ratio of 0.5 hours to 90 minutes.
Using Division
To find the ratio, we can divide 0.5 by 90.
0.5 / 90 = 1/180
So, the ratio of 30 minutes to 1.5 hours is 1:180.
Real-World Applications
Understanding how to find the ratio of time is essential in various real-world applications, such as:
- Cooking: When a recipe calls for a certain amount of time, it's essential to understand how to convert between minutes and hours to ensure that the dish is cooked to perfection.
- Travel: When planning a trip, it's crucial to understand how to convert between hours and minutes to ensure that you arrive at your destination on time.
- Sports: In sports, time is a critical factor. Understanding how to find the ratio of time can help athletes and coaches optimize their performance and make informed decisions.
Conclusion
In conclusion, finding the ratio of 30 minutes to 1.5 hours requires an understanding of time conversion and how to use division and multiplication to convert between minutes and hours. By applying this knowledge, we can find the ratio and understand how to use it in various real-world applications.
