Introduction

In everyday life, we often encounter measurements in different units, such as inches and feet. Converting between these units is an essential skill in mathematics, particularly in measurement and conversion problems. In this article, we will explore the factor-label method, a simple and effective technique for converting between different units. We will use this method to convert 104 inches to feet, rounding our answer to the nearest tenth as needed.

Understanding the Factor-Label Method

The factor-label method is a technique used to convert between different units by multiplying or dividing the given value by a conversion factor. A conversion factor is a ratio of two equivalent values, such as 1 foot = 12 inches. To use the factor-label method, we need to identify the given value, the conversion factor, and the desired unit.

Step 1: Identify the Given Value and Conversion Factor

In this problem, the given value is 104 inches, and the conversion factor is 1 foot = 12 inches. We want to convert 104 inches to feet.

Step 2: Set Up the Conversion Equation

To set up the conversion equation, we need to multiply the given value by the conversion factor. In this case, we will multiply 104 inches by 1 foot/12 inches.

Step 3: Simplify the Equation

To simplify the equation, we need to cancel out the common units. In this case, we can cancel out the inches unit by dividing both sides of the equation by 12.

Step 4: Solve for the Desired Unit

After simplifying the equation, we can solve for the desired unit, which is feet.

Step 5: Round the Answer to the Nearest Tenth

Finally, we need to round our answer to the nearest tenth as needed.

The Factor-Label Method in Action

Let's apply the factor-label method to convert 104 inches to feet.

Step 1: Identify the Given Value and Conversion Factor

Given value: 104 inches
Conversion factor: 1 foot = 12 inches

Step 2: Set Up the Conversion Equation

104 inches × (1 foot / 12 inches) = ?

Step 3: Simplify the Equation

To simplify the equation, we can cancel out the inches unit by dividing both sides of the equation by 12.

104 ÷ 12 = 8.67

Step 4: Solve for the Desired Unit

The desired unit is feet, so we can write the equation as:

104 inches = 8.67 feet

Step 5: Round the Answer to the Nearest Tenth

Rounding 8.67 to the nearest tenth, we get:

8.7 feet

Conclusion

In this article, we used the factor-label method to convert 104 inches to feet. We identified the given value and conversion factor, set up the conversion equation, simplified the equation, solved for the desired unit, and rounded the answer to the nearest tenth. The factor-label method is a simple and effective technique for converting between different units, and it can be applied to a wide range of measurement and conversion problems.
