Detailed Explanation:

First, let's start by looking at the basic multiplication process. To multiply 129 by a number, we need to add 129 to itself, the number of times specified by the multiplier. For example, if we want to multiply 129 by 5, we would add 129 to itself 5 times to get 645. This process can be represented visually using a multiplication table, a grid that shows the product of each combination of numbers from 1 to 9. The table below shows the multiplication of 129 by each of the numbers from 1 to 10:

As you can see, the multiplication of 129 is a straightforward process that follows a predictable pattern. However, some techniques can make this process even more accessible and more efficient.

One of the most common techniques used in multiplication is the commutative property. This property states that the order in which numbers are multiplied does not affect the product. For example, the product of 129 ✕ 5 is the same as that of 5 ✕ 129, which is 645. This property can be handy when multiplying more significant numbers, as it allows us to rearrange the factors more conveniently.

Another helpful technique is multiplication by 10, 100, or 1000. These numbers are easy to multiply because they are simply the result of adding zeros to the end of a number. To multiply 129 by 10, we merely need to add a zero to the end of 129 to get 1290. Similarly, to multiply 129 by 100, we need to add two zeros to the end of 129 to get 12900. This technique can be beneficial when multiplying more significant numbers, as it allows us to break the multiplication down into smaller and more manageable steps.

Finally, we can also use the distributive property to make the multiplication of 129 easier. According to the distributive property of multiplication, the first number can be distributed to both of the other numbers and multiplied by each of them separately before adding the results to get the same outcome as multiplying the first number by the sum. For example, if we want to multiply 129 by 7 (i.e 5+2), we can use the distributive property to break the multiplication down into two smaller multiplications:

129\times 7=129\times (5+2) = (129\times 5) + (129\times 2).

This technique can be very useful when multiplying more significant numbers, as it allows us to break the multiplication down into smaller and more manageable steps.

Solved Problems:

1. The price of 1 chocolate is Rs 1/- what will the price of 129 chocolate be?

Solution:

here 1 chocolate = 1/- Rs

129 chocolate =?

using the multiplication table of 129,

1 x 129 = 129

So the price of 129 chocolates = 129/- Rs

2. What is the area of a rectangle that is 129 inches long and 100 inches wide?

Solution:

If you need to calculate the area of a rectangle that is 129 inches long and 100 inches wide, you would multiply the length by the width to get the area, which would be 129 x 100 = 12900 square inches.

3. What is the total cost of three items that each cost Rs 129/-?

Solution:

If you want to buy three items that each cost Rs 129/-, you can multiply 129 by 3 to find that the total cost is Rs 387/-.

Conclusion:

In conclusion, the multiplication of 129 is a fundamental mathematical operation essential for math success. We can make this process easier and more efficient by using the techniques discussed in this article, such as the commutative property, multiplication by 10, 100, or 1000, and the distributive property. By understanding and applying these techniques, we can improve our multiplication skills and become more confident and booming in maths.
