Step-by-Step Breakdown of the Calculation

The given calculation is 225 * 63 / 2000. To solve this, we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). In this case, we have multiplication and division, which are performed from left to right. First, we multiply 225 by 63. This step involves multiplying two three-digit numbers, which can be done using traditional long multiplication or a calculator for efficiency. The result of this multiplication is 14175. This is a crucial intermediate step, as it forms the numerator of our eventual fraction. Now that we have the product of the first two numbers, we move on to the division operation. We will divide the result, 14175, by 2000. This division can be performed using long division or a calculator. The result of this division is 7.0875. This is the final answer to our calculation. It's important to note that this answer is a decimal number, which is perfectly acceptable. In some cases, you might be asked to round the answer to a specific number of decimal places, depending on the context of the problem. Understanding the step-by-step process is crucial for ensuring accuracy and building confidence in your mathematical abilities. By breaking down the calculation into smaller, manageable steps, we can avoid errors and gain a deeper understanding of the underlying mathematical principles. This approach is applicable to a wide range of mathematical problems, making it a valuable skill to develop. So, let's continue to explore the nuances of this calculation and its applications.

Performing the Multiplication: 225 * 63

The multiplication of 225 and 63 is a fundamental arithmetic operation that requires careful attention to detail. To perform this multiplication, we can use the traditional long multiplication method, which involves multiplying each digit of one number by each digit of the other number and then adding the results. Let's break down the process step by step. First, we multiply 225 by the ones digit of 63, which is 3. This gives us 225 * 3 = 675. We write this down as the first partial product. Next, we multiply 225 by the tens digit of 63, which is 6. However, since 6 is in the tens place, we are actually multiplying 225 by 60. This gives us 225 * 60 = 13500. We write this down as the second partial product, making sure to align the digits correctly (i.e., the ones digit of 13500 should be in the tens place). Now, we add the two partial products together: 675 + 13500 = 14175. This is the result of multiplying 225 by 63. Alternatively, you can use a calculator to verify this result. Understanding the long multiplication method is crucial for building a strong foundation in arithmetic. It helps to reinforce the concept of place value and the distributive property of multiplication. While calculators can be useful for quick calculations, knowing how to perform multiplication manually is essential for developing mathematical fluency. This skill is not only useful for solving mathematical problems but also for everyday situations, such as calculating costs and measurements. So, let's move on to the next step of our calculation, which involves dividing the result of this multiplication by 2000.

Dividing the Result: 14175 / 2000

Now that we have the result of the multiplication (14175), the next step is to divide it by 2000. This division operation will give us the final answer to our calculation. We can perform this division using long division or a calculator. Let's explore both methods. Using long division, we would set up the problem as 14175 ÷ 2000. We then determine how many times 2000 goes into 14175. Since 2000 * 7 = 14000, we know that 2000 goes into 14175 seven times. We write 7 as the quotient and subtract 14000 from 14175, which gives us a remainder of 175. To continue the division, we add a decimal point to the quotient and bring down a zero to the remainder, making it 1750. Now we determine how many times 2000 goes into 1750. Since 2000 is larger than 1750, it goes in zero times. We write 0 after the decimal point in the quotient and bring down another zero, making the remainder 17500. Now we determine how many times 2000 goes into 17500. Since 2000 * 8 = 16000, we know that 2000 goes into 17500 eight times. We write 8 after the 0 in the quotient and subtract 16000 from 17500, which gives us a remainder of 1500. We bring down another zero, making the remainder 15000. Now we determine how many times 2000 goes into 15000. Since 2000 * 7 = 14000, we know that 2000 goes into 15000 seven times. We write 7 after the 8 in the quotient and subtract 14000 from 15000, which gives us a remainder of 1000. We bring down another zero, making the remainder 10000. Now we determine how many times 2000 goes into 10000. Since 2000 * 5 = 10000, we know that 2000 goes into 10000 five times. We write 5 after the 7 in the quotient, and the remainder is 0. Therefore, the result of the division is 7.0875. Using a calculator, we can simply divide 14175 by 2000, which will also give us the result 7.0875. Understanding both long division and calculator methods is important for developing a comprehensive understanding of division. Long division helps to reinforce the concept of place value and the division algorithm, while calculators provide a quick and efficient way to perform calculations. So, we have successfully completed the division operation and arrived at the final answer of 7.0875.

Final Result and Interpretation

After performing the multiplication and division, we arrive at the final result of 7.0875. This number represents the value obtained when 225 is multiplied by 63 and then divided by 2000. The result is a decimal number, which indicates that the division did not result in a whole number. Understanding the interpretation of this result is crucial in various contexts. For instance, if this calculation represented a ratio or proportion, the result 7.0875 would indicate the relationship between the quantities involved. In financial calculations, this result could represent an interest rate, a return on investment, or a profit margin. In scientific applications, it could represent a measurement, a concentration, or a physical constant. The interpretation of the result depends heavily on the specific context in which the calculation is applied. It's important to consider the units of measurement and the significance of the numbers involved. For example, if the numbers represented quantities in different units, the result would need to be interpreted accordingly. Similarly, if the numbers represented measurements with a certain degree of uncertainty, the result would also have a degree of uncertainty. Understanding the limitations of the calculation and the potential sources of error is crucial for making informed decisions based on the result. In conclusion, the final result of 7.0875 is more than just a number; it's a piece of information that needs to be interpreted within the context of the problem.
