Converting Miles to Kilometers: A Guide to Unit Conversion Fractions

Understanding the Basics of Unit Conversion

When working with different units of measurement, it's essential to understand how to convert between them. In this article, we'll focus on converting miles to kilometers, a common task in mathematics and everyday life. We'll explore the concept of unit conversion fractions and provide you with the correct fraction to use when converting 25 miles to kilometers.

What is a Unit Conversion Fraction?

A unit conversion fraction is a mathematical expression that represents the relationship between two different units of measurement. It's a ratio of one unit to another, usually expressed as a fraction. For example, if we want to convert miles to kilometers, we need to know the relationship between these two units.

The Relationship Between Miles and Kilometers

One mile is equal to 1.60934 kilometers. This is the conversion factor we'll use to convert miles to kilometers. To create a unit conversion fraction, we'll use this conversion factor and express it as a fraction.

Creating a Unit Conversion Fraction

To create a unit conversion fraction, we'll use the conversion factor and express it as a fraction. In this case, we'll use the conversion factor 1.60934 km/mi. We'll express this as a fraction by writing it as:

1 km0.621371 mi\frac{1 \text{ km}}{0.621371 \text{ mi}}

This fraction represents the relationship between kilometers and miles. To convert miles to kilometers, we'll use this fraction and multiply the number of miles by the fraction.

Choosing the Correct Unit Conversion Fraction

Now that we have the correct unit conversion fraction, let's look at the options provided in the problem. We need to choose the correct fraction to use when converting 25 miles to kilometers.

A. 1 km0.6 mi\frac{1 \text{ km}}{0.6 \text{ mi}}

B. 1 mi0.6 km\frac{1 \text{ mi}}{0.6 \text{ km}}

C. 1 km0.621371 mi\frac{1 \text{ km}}{0.621371 \text{ mi}}

Analyzing the Options

Let's analyze each option and determine which one is correct.

Option A: 1 km0.6 mi\frac{1 \text{ km}}{0.6 \text{ mi}}

This fraction is incorrect because it's not the correct conversion factor. The conversion factor is 1.60934 km/mi, not 0.6 km/mi.

Option B: 1 mi0.6 km\frac{1 \text{ mi}}{0.6 \text{ km}}

This fraction is also incorrect because it's not the correct conversion factor. The conversion factor is 1.60934 km/mi, not 0.6 km/mi.

Option C: 1 km0.621371 mi\frac{1 \text{ km}}{0.621371 \text{ mi}}

This fraction is correct because it represents the correct conversion factor. We can use this fraction to convert 25 miles to kilometers.

Converting 25 Miles to Kilometers

Now that we have the correct unit conversion fraction, let's use it to convert 25 miles to kilometers.

25 mi1×1 km0.621371 mi=40.233 km\frac{25 \text{ mi}}{1} \times \frac{1 \text{ km}}{0.621371 \text{ mi}} = 40.233 \text{ km}

Conclusion

In this article, we explored the concept of unit conversion fractions and provided you with the correct fraction to use when converting miles to kilometers. We analyzed the options provided in the problem and determined that option C is the correct choice. We then used the correct unit conversion fraction to convert 25 miles to kilometers. By understanding unit conversion fractions, you'll be able to perform conversions with ease and accuracy.
