Solution: To find the average length of the two ribbons, we add their lengths and divide by 2. The total length is \(3.2 + 7.8 = 11.0\) inches. Dividing by 2, we get \(\frac{11.0}{2} = 5.5\) inches. Thus, the average length is \(\boxed{5.5}\) inches.
["How to Calculate the Average Length of Two Ribbons: A Simple Step-by-Step Guide", "Finding the average length of two ribbons is a straightforward yet essential measurement skill, useful for crafting, gift wrapping, tailoring, and everyday planning. Whether you're comparing ribbon sizes for a DIY project or arranging decorative elements, knowing how to compute the average ensures precision and consistency. In this article, we’ll explore the clear method to calculate the average ribbon length, using a real-world example to make the process easy to follow.", "### The Simple Formula for Average Length", "The average of two numbers—like ribbon lengths—is found by adding the lengths together and dividing the sum by two. This basic mathematical principle applies perfectly to ribbon measurements:", "[\n\ ext{Average Length} = \frac{\ ext{Length}_1 + \ ext{Length}_2}{2}\n]", "### Step-by-Step Example: Finding the Average Ribbon Length", "Let’s apply this method with a practical example. Suppose you have two ribbons with the following lengths:\n- Ribbon A: 3.2 inches\n- Ribbon B: 7.8 inches", "Step 1: Add the two lengths\n[\n3.2 + 7.8 = 11.0 \ ext{ inches}\n]", "Step 2: Divide the total by 2\n[\n\frac{11.0}{2} = 5.5 \ ext{ inches}\n]", "So, the average length of the ribbons is exactly:\n[\n\boxed{5.5} \ ext{ inches}\n]", "### Why This Method Works", "Using the average helps average out differences in length, making it ideal for comparing materials or mixing ribbons of different sizes.
