Introduction
In the realm of mathematics, proportions play a crucial role in establishing relationships between quantities. Understanding proportions is fundamental not only in academic settings but also in various real-world applications, from scaling recipes in the kitchen to calculating distances on maps. This comprehensive guide will walk you through the process of solving a specific proportion, , and express the answer in its exact simplest form. Mastering the techniques for solving proportions equips you with valuable problem-solving skills applicable across diverse fields. This article aims to provide a clear, step-by-step explanation, ensuring you grasp the underlying concepts and can confidently tackle similar problems.
Understanding Proportions
Before diving into the solution, it's essential to understand the core concept of a proportion. A proportion is essentially a statement of equality between two ratios or fractions. In simpler terms, it asserts that two fractions are equivalent. For instance, if we say that , we are stating that the ratio of a to b is the same as the ratio of c to d. This concept is deeply rooted in the principles of scaling and equivalence, which are fundamental to many mathematical operations. Proportions are not just abstract mathematical concepts; they have practical applications in various scenarios. Consider situations like scaling a recipe for a larger group, where maintaining the proportion of ingredients is crucial, or calculating distances on a map, where the scale is a proportion that relates map distances to real-world distances. Understanding proportions provides a foundation for solving problems in everyday contexts.
To solidify your understanding, let's consider some real-world examples. Imagine you are baking a cake and the recipe calls for 2 cups of flour for every 1 cup of sugar. This ratio, , represents a proportion. If you want to bake a larger cake and need to use 4 cups of flour, you'll need to maintain this proportion by using 2 cups of sugar. This can be represented as the proportion . Another example is in map reading. If a map has a scale of 1 inch to 10 miles, this is a proportion. If two cities are 3 inches apart on the map, you can use the proportion to find the actual distance between them, where x represents the unknown distance. These examples illustrate how proportions are used to maintain consistent relationships between quantities, making them a powerful tool in various fields. By grasping the fundamental concept of proportions, you can approach a wide range of problems with confidence, knowing that you have a solid understanding of the underlying principles.
Setting up the Proportion
The given proportion is . Here, we have two ratios set equal to each other. Our goal is to find the value of t that makes this equation true. In this proportion, 13 and 65 are the numerators (the numbers on top of the fraction), while 6 and t are the denominators (the numbers on the bottom). The proportion states that the ratio of 13 to 6 is equivalent to the ratio of 65 to t. Before we jump into solving, it's important to ensure that the proportion is set up correctly. The corresponding parts of the ratios should be in the same positions. In this case, the numerators represent one quantity, and the denominators represent another, ensuring the proportion is logically structured. Misinterpreting the setup can lead to incorrect solutions, so a careful initial assessment is crucial. By verifying that the proportion is correctly set up, we can proceed with confidence towards finding the value of t and expressing it in its simplest form.
Solving for t
To solve for t in the proportion , we can use the method of cross-multiplication. Cross-multiplication is a technique used to solve proportions by multiplying the numerator of one fraction by the denominator of the other fraction and setting these products equal to each other. This method is based on the fundamental property of proportions, which states that if , then ad = bc. Applying this to our proportion, we multiply 13 by t and 6 by 65, which gives us the equation 13t = 6 * 65. This step transforms the proportion into a linear equation, which is easier to solve. Cross-multiplication is a powerful tool because it eliminates the fractions, simplifying the equation and making it more manageable. By understanding and applying this technique, you can efficiently solve for the unknown variable in any proportion. This method is not only effective but also widely applicable, making it a valuable skill in mathematical problem-solving.
Now that we have the equation 13t = 6 * 65, the next step is to isolate t. To isolate t, we need to divide both sides of the equation by 13. This is a fundamental algebraic principle: performing the same operation on both sides of an equation maintains the equality. So, we divide both 13t and 6 * 65 by 13, which gives us t = . Before we perform the multiplication, it's a good practice to look for opportunities to simplify. We can see that 65 is divisible by 13 (65 = 13 * 5). This allows us to simplify the fraction before multiplying, which reduces the size of the numbers we are working with and can prevent errors. Simplifying early in the process is a key strategy in mathematics, as it often makes the calculations easier and more straightforward. By recognizing the divisibility of 65 by 13, we can simplify the equation and proceed towards finding the value of t in a more efficient manner.
Simplifying the Solution
We have arrived at the equation t = . As we noticed earlier, 65 is divisible by 13. Specifically, 65 divided by 13 is 5. So, we can rewrite the equation as t = . Now, we can cancel out the 13 in the numerator and the denominator, which simplifies the equation to t = 6 * 5. This simplification step is crucial because it reduces the fraction to its simplest form, making the final calculation straightforward. Cancelling common factors is a fundamental technique in fraction manipulation, and it is essential for expressing solutions in their simplest terms. By recognizing and applying this simplification, we avoid unnecessary calculations and arrive at the final answer more efficiently. This process not only makes the solution cleaner but also demonstrates a deeper understanding of mathematical principles.
Now, we simply multiply 6 by 5 to find the value of t. 6 multiplied by 5 equals 30. Therefore, t = 30. This is the exact value of t that satisfies the given proportion. The solution is expressed as a whole number, which is the simplest form in this case. It's always a good practice to double-check the solution by substituting it back into the original proportion to ensure it holds true. In this case, should be equal to . We can simplify by dividing both the numerator and the denominator by 5, which gives us . This confirms that our solution, t = 30, is correct. By verifying the solution, we ensure accuracy and gain confidence in our problem-solving process. This step is an integral part of mathematical practice and helps in solidifying understanding.
Final Answer
After following the step-by-step process of cross-multiplication and simplification, we have found the value of t that solves the proportion . The final answer, expressed in exact simplest form, is t = 30. This solution represents the value that makes the two ratios in the proportion equal. We arrived at this answer by first setting up the proportion correctly, then applying the method of cross-multiplication to transform the proportion into a linear equation. We then isolated t by dividing both sides of the equation by 13 and simplified the resulting fraction by canceling out common factors. Finally, we performed the multiplication to find the value of t. Throughout this process, we emphasized the importance of simplification and verification to ensure accuracy. This detailed walkthrough demonstrates not only the solution but also the underlying principles and techniques involved in solving proportions, providing a comprehensive understanding of the topic.
