Introduction

In mathematics, patterns play a crucial role in solving various problems, including division. One common pattern is the multiplication of a decimal number by a power of 10 to shift its decimal point. In this article, we will explain how to use this pattern to find $$35.6 \div 100$$.

Understanding the Pattern

The pattern we will use is based on the concept of multiplying a decimal number by a power of 10 to shift its decimal point. For example, if we want to find $$35.6 \div 10$$, we can multiply 35.6 by 0.1 (which is 1/10) to get 3.56. Similarly, if we want to find $$35.6 \div 100$$, we can multiply 35.6 by 0.01 (which is 1/100) to get 0.356.

Applying the Pattern to Find $$35.6 \div 100$$

To find $$35.6 \div 100$$, we can use the pattern we discussed earlier. We will multiply 35.6 by 0.01 (which is 1/100) to get the result.

Step 1: Multiply 35.6 by 0.01

To multiply 35.6 by 0.01, we can simply move the decimal point two places to the left. This will give us 0.356.

Step 2: Write the Result

The result of multiplying 35.6 by 0.01 is 0.356. Therefore, $$35.6 \div 100 = 0.356$$.

Example Problems

To reinforce our understanding of the pattern, let's consider a few example problems.

Example 1: $$56.2 \div 10$$

To find $$56.2 \div 10$$, we can multiply 56.2 by 0.1 (which is 1/10) to get 5.62.

Example 2: $$98.5 \div 1000$$

To find $$98.5 \div 1000$$, we can multiply 98.5 by 0.001 (which is 1/1000) to get 0.0985.

Example 3: $$23.1 \div 1000$$

To find $$23.1 \div 1000$$, we can multiply 23.1 by 0.001 (which is 1/1000) to get 0.0231.

Conclusion

In this article, we explained how to use a pattern to find $$35.6 \div 100$$. We discussed the concept of multiplying a decimal number by a power of 10 to shift its decimal point and applied this pattern to find the result. We also provided example problems to reinforce our understanding of the pattern. By using this pattern, we can easily find the result of dividing a decimal number by a power of 10.
