Hey there, math enthusiasts! Today, we're diving deep into the fascinating world of fraction arithmetic. Get ready to sharpen your pencils and flex your mental muscles as we tackle a seemingly complex equation: [(7/12 + 3/4) - (1/6 - 3/8)]. But don't worry, we'll break it down step by step, making sure everyone understands the process. We'll explore the fundamental concepts of adding, subtracting, and simplifying fractions, so you'll not only solve this particular problem but also gain the skills to conquer any fraction-related challenge that comes your way. Let's embark on this mathematical journey together!
Understanding the Basics of Fractions
Before we jump into the main equation, let's quickly revisit the basics of fractions. A fraction represents a part of a whole and is written in the form of a/b, where 'a' is the numerator (the top number) and 'b' is the denominator (the bottom number). The denominator tells us how many equal parts the whole is divided into, and the numerator tells us how many of those parts we're considering. For example, in the fraction 1/2, the whole is divided into two equal parts, and we're considering one of those parts. Similarly, 3/4 means we're considering three parts out of a total of four equal parts.
When dealing with fractions, it's crucial to understand the concepts of equivalent fractions and simplification. Equivalent fractions are fractions that represent the same value, even though they have different numerators and denominators. For instance, 1/2 and 2/4 are equivalent fractions because they both represent half of a whole. To find equivalent fractions, you can multiply or divide both the numerator and the denominator by the same non-zero number. Simplifying fractions involves reducing them to their lowest terms by dividing both the numerator and the denominator by their greatest common divisor (GCD). This process ensures that the fraction is expressed in its simplest form, making it easier to work with in calculations.
Tackling the Equation Step-by-Step
Now, let's get to the heart of the matter and solve the equation: [(7/12 + 3/4) - (1/6 - 3/8)]. To solve this equation, we'll follow the order of operations, which dictates that we perform operations within parentheses first. So, we'll start by addressing the two sets of parentheses separately. Within each set of parentheses, we'll need to add or subtract fractions, which requires finding a common denominator.
Step 1: Solving the First Parenthesis (7/12 + 3/4)
The first parenthesis contains the addition of two fractions: 7/12 and 3/4. To add these fractions, we need to find a common denominator. The common denominator is the least common multiple (LCM) of the denominators, which in this case are 12 and 4. The LCM of 12 and 4 is 12, so we'll use 12 as our common denominator. We need to convert 3/4 into an equivalent fraction with a denominator of 12. To do this, we multiply both the numerator and the denominator of 3/4 by 3, which gives us 9/12. Now we can add the fractions: 7/12 + 9/12 = (7 + 9)/12 = 16/12. This fraction can be simplified by dividing both the numerator and the denominator by their GCD, which is 4. So, 16/12 simplifies to 4/3.
Step 2: Solving the Second Parenthesis (1/6 - 3/8)
Next, we move on to the second parenthesis, which involves the subtraction of two fractions: 1/6 and 3/8. Again, we need to find a common denominator. The LCM of 6 and 8 is 24, so we'll use 24 as our common denominator. We need to convert both fractions into equivalent fractions with a denominator of 24. To convert 1/6, we multiply both the numerator and the denominator by 4, which gives us 4/24. To convert 3/8, we multiply both the numerator and the denominator by 3, which gives us 9/24. Now we can subtract the fractions: 4/24 - 9/24 = (4 - 9)/24 = -5/24.
Step 3: Combining the Results
Now that we've solved both sets of parentheses, we can combine the results. We have 4/3 from the first parenthesis and -5/24 from the second parenthesis. The original equation was a subtraction between the two parentheses, so we need to subtract -5/24 from 4/3. Subtracting a negative number is the same as adding its positive counterpart, so we're essentially adding 5/24 to 4/3. To do this, we need to find a common denominator once more. The LCM of 3 and 24 is 24, so we'll use 24 as our common denominator. We need to convert 4/3 into an equivalent fraction with a denominator of 24. To do this, we multiply both the numerator and the denominator of 4/3 by 8, which gives us 32/24. Now we can add the fractions: 32/24 + 5/24 = (32 + 5)/24 = 37/24.
Final Result and its Significance
Therefore, the final answer to the equation [(7/12 + 3/4) - (1/6 - 3/8)] is 37/24. This fraction is in its simplest form because 37 and 24 have no common factors other than 1. The result, 37/24, is an improper fraction, meaning the numerator is greater than the denominator. We can also express it as a mixed number, which is 1 and 13/24. This means that the value is one whole and thirteen twenty-fourths. Understanding how to perform operations with fractions is fundamental in various areas of mathematics, including algebra, calculus, and geometry. It's also essential in real-world applications, such as cooking, construction, and finance.
Practice Makes Perfect: Mastering Fraction Arithmetic
