The Standard Method: How to Multiply 7605 by 75 Step-by-Step

The most common and reliable way to find the product of 7605 multiplied by 75 is by using the standard multiplication method, which involves breaking the problem down into smaller, manageable steps. This technique works by multiplying the larger number (7,605) first by the ones digit (5) of the smaller number, and then by the tens digit (7). This structured approach makes sure every digit is multiplied correctly.

Breaking Down the Multiplication 7605×75

This method requires us to perform two separate multiplication problems, known as partial products, and then add them together. We take the four-digit number, 7,605, and multiply it by each digit in the two-digit number, 75. It is crucial to be organized during this process to avoid mixing up the numbers you need to carry over.

Step 1: Multiply 7605 by the Ones Digit (5)

In this first step, we simply calculate $7605 \times 5$. We start from the rightmost digit of 7,605 (which is 5) and multiply it by 5.

• 5x 5 = 25. Write down 5 and carry over 2.
• 0 x 5 = 0. Add the carried over 2, making it 2. Write down 2.
• 6 x 5 = 30. Write down 0 and carry over 3.
• 7 x 5 = 35. Add the carried over 3, making it 38. Write down 38.

The result of the first partial product 7605×5 is 38,025.

Step 2: Multiply 7605 by the Tens Digit (70)

Now we multiply 7,605 by the tens digit, which is 7. Since the 7 is in the tens place, we are really multiplying by 70. The most important rule here is to write a zero placeholder (0) below the ones digit of our first partial product (the 5 in 38,025). This shifts our entire answer one place to the left, correctly representing the multiplication by a tens number.

• Start by placing a 0.
• 5 x 7 = 35. Write down 5 next to the 0 and carry over 3.
• 0 x 7 = 0. Add the carried over 3, making it 3. Write down 3.
• 6 x 7 = 42. Write down 2 and carry over 4.
• 7 x 7 = 49. Add the carried over 4, making it 53. Write down 53.

The result of the second partial product 7605×70 is 532,350.

Step 3: Add the Partial Products Together

The final step in finding the answer to 7605×75 is simply adding the two results we found in the previous steps.

Description	Calculation
First Partial Product ($7605 \times 5$)	38,025
Second Partial Product ($7605 \times 70$)	+ 532,350
Final Product of 7605×75	570,375

Therefore, the ultimate answer when you calculate 7605×75 is 570,375. This method is effective because it systematically accounts for every number, ensuring a precise and reliable result.

Alternative Calculation: Using the Distributive Property for 7605×75

While the standard method is the most common, another powerful tool in mathematics is the Distributive Property. This property tells us that multiplying a number by a sum is the same as multiplying the number by each part of the sum separately and then adding the results. This can often make mental math easier or provide a good way to check your work for 7605×75

The core idea is to break down the number 75 into two easier parts: 70 + 5.

7605×75 = 7605 x (70 + 5)

This allows us to transform the original problem of 7605 multiplied by 75 into two simpler multiplications:

• Multiply 7605 by 70: This is relatively easy because we can just multiply by 7 and then add a zero to the end.
  • 7605×70 = 532,350.
• Multiply 7605 by 5: We already did this in the standard method’s first step.
  • 7605×5 = 38,025.

The final step is to add these two products together.

532,350 + 38,025 = 570,375

As you can see, the Distributive Property confirms the answer: 7605×75 is indeed 570,375. This demonstrates how different mathematical rules can lead to the same accurate solution, giving you confidence in your final calculation.

• Forgetting the Placeholder Zero: When multiplying by the tens digit (7, or 70), you must place a zero in the ones column of the second partial product. If you forget this zero, your second number (53,235) will be ten times smaller than it should be, resulting in a dramatically wrong final answer. Always remember the zero placeholder!
• Errors in Carrying Over: When a product is 10 or greater, you must “carry over” the tens digit to the next column. Mistakes often happen when adding the carried-over number incorrectly or forgetting to add it at all. A neat, organized layout with small notes of the carried numbers can prevent this.
• Misaligning Digits During Addition: The final step requires adding the two partial products (38,025 and 532,350). If your numbers are not perfectly lined up by their place value (ones under ones, tens under tens, etc.), you will add the wrong numbers together and get an incorrect sum. Use graph paper or draw lines to keep your columns straight.
