Solving Fraction Arithmetic: A Step-by-Step Guide
Hey there, math enthusiasts! Today, we're diving into a fraction arithmetic problem: 2 4/9 * 6/11 - 25/27. Don't worry if fractions sometimes feel like a puzzle; we'll break it down step by step, making it easy to understand. Let's get started and make fractions fun! I will provide the step-by-step solution, ensuring you grasp the process from start to finish. We'll start by addressing the mixed number, converting it to an improper fraction. Next, we'll handle the multiplication, simplifying where possible. Finally, we'll tackle the subtraction, making sure we have a common denominator. This method makes it easier to approach similar fraction problems confidently.
First, let's look at the problem again: 2 4/9 * 6/11 - 25/27. The first thing we want to do is convert the mixed number 2 4/9 into an improper fraction. To do this, multiply the whole number (2) by the denominator (9) and add the numerator (4). So, (2 * 9) + 4 = 18 + 4 = 22. This result becomes the new numerator, and we keep the same denominator, which is 9. Therefore, 2 4/9 becomes 22/9. Now our problem looks like this: 22/9 * 6/11 - 25/27. You see, this makes the next steps so much easier! By changing that mixed number, we've set ourselves up for a smooth ride through this problem. Remember, converting mixed numbers is often the first and most crucial step in fraction arithmetic, guys!
Step-by-Step Solution: Breaking Down the Problem
Now, let's dive deep into solving our fraction problem step by step. We have the expression: 22/9 * 6/11 - 25/27. Our goal is to simplify this expression to find the final answer. We'll break down the process into smaller, manageable steps, which will help us understand each action. This approach not only makes the calculation easier but also helps to grasp the underlying concepts of fraction arithmetic. This method helps to clarify any confusion about how to handle fractions and ensures a strong understanding of mathematical principles. It also shows you how to approach complex problems by breaking them into smaller, more solvable parts. So, get ready to see the solution unfold systematically. Don't worry; it's simpler than it looks!
Converting the Mixed Number
As we previously discussed, the first step is to convert the mixed number 2 4/9 into an improper fraction. The mixed number 2 4/9 needs to be converted into an improper fraction. To do this, we multiply the whole number (2) by the denominator (9) and add the numerator (4). This gives us (2 * 9) + 4 = 18 + 4 = 22. We keep the denominator as 9. So, 2 4/9 becomes 22/9. This step sets up the rest of the problem, and changing a mixed number into an improper fraction simplifies the process, making it easier to perform the necessary calculations. This initial conversion is critical because it allows us to handle all parts of the problem uniformly and correctly.
Multiplication of Fractions
Next, we'll perform the multiplication of the fractions. We have 22/9 * 6/11. When multiplying fractions, we multiply the numerators (the top numbers) together and the denominators (the bottom numbers) together. So, we multiply 22 by 6 and 9 by 11. However, before we do this, it's often helpful to simplify the fractions by canceling out common factors. We can see that 22 and 11 have a common factor of 11, and we can divide both by 11. This simplifies 22 to 2 and 11 to 1. Also, 6 and 9 have a common factor of 3, so we can divide both by 3, making 6 become 2, and 9 become 3. Now our problem looks like this: 2/3 * 2/1. Multiply across, we have (2 * 2)/(3 * 1), which gives us 4/3. This simplification step makes our calculations less cumbersome, and working with smaller numbers is always better. Remember, guys, simplifying before multiplying is a time-saver!
Subtraction of Fractions
Now, we move on to the subtraction part of the problem. We need to subtract 25/27 from the result we obtained from the multiplication, which was 4/3. So, we have 4/3 - 25/27. Before we can subtract, we need to ensure that both fractions have the same denominator, which is called finding a common denominator. The easiest way to do this is to find the least common multiple (LCM) of the denominators, which are 3 and 27. The LCM of 3 and 27 is 27. We change the first fraction, 4/3, to have a denominator of 27. To do this, multiply both the numerator and the denominator of 4/3 by 9 (because 3 * 9 = 27). This gives us (4 * 9)/(3 * 9) = 36/27. Now our subtraction problem looks like this: 36/27 - 25/27. With a common denominator, we can subtract the numerators and keep the same denominator: (36 - 25)/27, which equals 11/27. The answer to the problem is 11/27.
Conclusion: The Final Answer
After going through all the steps, from converting the mixed number to performing the multiplication and subtraction, we have finally arrived at our solution. The answer to the original fraction arithmetic problem, 2 4/9 * 6/11 - 25/27, is 11/27. Remember how we started with a mixed number and complex operations? We have broken it down into easier parts and used simplification techniques. The key takeaway from this exercise is that fraction arithmetic can be manageable when approached systematically. Every step, from converting mixed numbers to finding common denominators, plays a vital role in arriving at the correct solution. Practice these steps with other fraction problems to boost your confidence and skills. Keep in mind that understanding and applying these methods makes tackling fractions much more accessible and less intimidating. Congratulations, you've successfully navigated a fraction arithmetic problem!
