In the given problem, ${\frac{5}{6} + \frac{3}{10} + \frac{7}{6}}$, we can readily observe that ${\frac{5}{6}}$ and ${\frac{7}{6}}$ have the same denominator, which is 6. Grouping these fractions together simplifies the addition process, allowing us to combine them directly before addressing the fraction with a different denominator. This strategy not only streamlines the calculations but also leverages the associative property of addition, which states that the way numbers are grouped in an addition problem does not affect the sum. By grouping like fractions, we set the stage for a more manageable and organized approach to the problem.

The associative property is a cornerstone of arithmetic, and its application here demonstrates a key problem-solving technique in mathematics: breaking down complex problems into simpler components. By recognizing the like fractions and strategically grouping them, we reduce the cognitive load and create a clear path toward the solution. This approach is particularly helpful when dealing with multiple fractions, as it allows us to tackle the problem in stages, minimizing the chances of errors and enhancing our understanding of the process.

Now that we have identified and grouped the like fractions, ${\frac{5}{6}}$ and ${\frac{7}{6}}$, the next step is to perform the addition. Adding fractions with the same denominator is straightforward: we simply add the numerators while keeping the denominator constant. In this case, we add 5 and 7, which gives us 12, and retain the denominator of 6. Thus, ${\frac{5}{6} + \frac{7}{6} = \frac{5+7}{6} = \frac{12}{6}}$. This step highlights a core principle of fraction addition, where the common denominator acts as the unit of measurement, and the numerators represent the number of these units being combined. The result, ${\frac{12}{6}}$, is an important intermediate value that we will use in the subsequent steps of the problem.

The simplicity of adding fractions with the same denominator underscores the importance of the common denominator concept. It allows us to treat fractions as quantities that can be directly added, much like adding whole numbers. The common denominator provides a consistent scale, ensuring that we are adding comparable parts of a whole. This concept is fundamental to understanding fraction arithmetic and forms the basis for more complex operations involving fractions. The result we obtained, ${\frac{12}{6}}$, is not only the sum of the like fractions but also a fraction that can be further simplified, which we will address in the next step. This connection between addition and simplification is a recurring theme in fraction arithmetic and demonstrates the interconnectedness of mathematical concepts.

Adding like fractions is a foundational skill that not only solves specific problems but also reinforces the underlying principles of fraction arithmetic. It demonstrates the power of common denominators in facilitating addition and lays the groundwork for more advanced operations.

Step 4: Adding the Remaining Fraction: ${2 + \frac{3}{10}}$

Having simplified ${\frac{5}{6} + \frac{7}{6}}$ to 2, we now need to add the remaining fraction, ${\frac{3}{10}}$, to this result. The problem now becomes ${2 + \frac{3}{10}}$. To add a whole number to a fraction, we can express the whole number as a fraction with the same denominator as the other fraction. In this case, we can express 2 as a fraction with a denominator of 10. To do this, we multiply 2 by ${\frac{10}{10}}$ (which is equal to 1), giving us ${2 \times \frac{10}{10} = \frac{20}{10}}$. Now, we can rewrite the problem as ${\frac{20}{10} + \frac{3}{10}}$, which involves adding two fractions with the same denominator. This transformation is a crucial step in unifying the terms and setting the stage for a straightforward addition process.

Expressing a whole number as a fraction with a specific denominator is a fundamental technique in fraction arithmetic, allowing us to seamlessly integrate whole numbers into fraction calculations.

The ability to confidently handle such calculations is a testament to mathematical proficiency and its practical relevance. The transformation of the problem to ${\frac{20}{10} + \frac{3}{10}}$ not only simplifies the addition process but also reinforces the importance of a common denominator in fraction arithmetic. This step is a crucial bridge between the simplification of like fractions and the final calculation, demonstrating the interconnectedness of mathematical operations and their application in solving real-world problems.

Step 5: Completing the Addition: ${\frac{20}{10} + \frac{3}{10}}$

Now that we have expressed both terms as fractions with the same denominator, the addition becomes straightforward. We are adding ${\frac{20}{10}}$ and ${\frac{3}{10}}$. To add fractions with the same denominator, we simply add the numerators and keep the denominator constant. So, we have ${\frac{20}{10} + \frac{3}{10} = \frac{20+3}{10} = \frac{23}{10}}$. This result, ${\frac{23}{10}}$, represents the sum of the original three fractions and is a valid answer. However, it is often desirable to express the result as a mixed number, which combines a whole number and a proper fraction. This form provides a more intuitive understanding of the quantity, especially in practical contexts. The conversion to a mixed number will be our next step in presenting the final solution.

Adding fractions with a common denominator is a fundamental operation in fraction arithmetic, and this step reinforces the principle that we are combining quantities that are measured in the same units. The denominator, in this case, 10, represents the size of the parts, and the numerators represent the number of these parts. By adding the numerators, we are essentially counting the total number of parts. The result, ${\frac{23}{10}}$, is an improper fraction, indicating that the numerator is larger than the denominator. While this is a perfectly valid answer, expressing it as a mixed number provides additional insight into the quantity. This conversion is a practical skill that enhances our ability to interpret and communicate mathematical results effectively.

Furthermore, the addition of ${\frac{20}{10}}$ and ${\frac{3}{10}}$ demonstrates the consistency and elegance of mathematical operations. The process of adding fractions with a common denominator is a clear and concise procedure that yields an accurate result. This consistency is a hallmark of mathematics and contributes to its reliability as a tool for problem-solving and analysis. The result, ${\frac{23}{10}}$, is not just a numerical answer; it is a representation of the total quantity resulting from the addition of the original fractions. This understanding is crucial for applying mathematical concepts to real-world situations and making informed decisions based on quantitative data. Therefore, mastering the addition of fractions is essential for developing mathematical fluency and problem-solving skills.

Step 6: Expressing the Result as a Mixed Number (Optional)

The fraction ${\frac{23}{10}}$ is an improper fraction, meaning the numerator (23) is greater than the denominator (10). While ${\frac{23}{10}}$ is a correct answer, it's often more intuitive to express it as a mixed number, which consists of a whole number and a proper fraction. To convert an improper fraction to a mixed number, we divide the numerator by the denominator. In this case, we divide 23 by 10. The quotient (the whole number result of the division) becomes the whole number part of the mixed number, and the remainder becomes the numerator of the fractional part, with the denominator remaining the same. When we divide 23 by 10, we get a quotient of 2 and a remainder of 3. Therefore, ${\frac{23}{10}}$ is equal to the mixed number 2 ${\frac{3}{10}}$. This representation provides a clearer sense of the magnitude of the fraction, as it explicitly shows the whole number part and the fractional part.

Converting improper fractions to mixed numbers is a valuable skill in mathematics, as it allows us to express quantities in a way that is often easier to understand and visualize. The mixed number 2 ${\frac{3}{10}}$ tells us immediately that the quantity is greater than 2 but less than 3, which can be more informative than the improper fraction ${\frac{23}{10}}$. This skill is particularly useful in practical applications, such as measuring ingredients for a recipe or calculating lengths and distances. The process of dividing the numerator by the denominator and expressing the result as a mixed number is a straightforward procedure that reinforces the relationship between improper fractions and mixed numbers. It also highlights the importance of understanding the meaning of the numerator, denominator, quotient, and remainder in the context of fractions.

Furthermore, expressing the result as a mixed number is a common practice in mathematical communication, as it often provides a more accessible and intuitive representation of the quantity. The mixed number 2 ${\frac{3}{10}}$ is a clear and concise way to convey the result of the addition problem, making it easier for others to understand and interpret. This skill is essential for effective communication in mathematics and related fields. The conversion from an improper fraction to a mixed number not only enhances our understanding of the quantity but also demonstrates our ability to present mathematical results in a clear and meaningful way.
