## Mastering Multiplication and Division of Decimals

Multiplying and dividing decimals are essential skills in mathematics that are used in various real-life scenarios, such as shopping, budgeting, and measurement. Understanding these concepts can help you manage everyday tasks more effectively.

##### Introduction

Multiplying and dividing decimals might seem complex, but with the right approach, it becomes straightforward. These operations involve understanding place value and aligning decimal points correctly. Let's break down the steps for each process.

###### Multiplication of Decimals

To multiply decimals, follow these steps:

**Ignore the decimals:**Multiply the numbers as if they were whole numbers.**Count decimal places:**Count the total number of decimal places in both of the original numbers.**Place the decimal:**In the product, place the decimal point so that it has the same number of decimal places as the total from step 2.

Example: Multiplying 2.5 by 1.3

Ignore the decimals and multiply 25 by 13:25 × 13 = 325

Count the decimal places: There is one decimal place in each number, so the total is 2.

Place the decimal point in the product to have two decimal places:3.25

So, 2.5 multiplied by 1.3 equals 3.25.

###### Division of Decimals

To divide decimals, follow these steps:

**Move the decimal:**Move the decimal point in the divisor to the right until it becomes a whole number. Do the same shift to the dividend.**Divide as usual:**Divide the numbers as if they were whole numbers.**Place the decimal:**Place the decimal point directly above its position in the dividend.

Example: Dividing 6.75 by 2.5

Move the decimal point in 2.5 to the right one place to make it 25. Do the same for 6.75, making it 67.5.

Divide 67.5 by 25:67.5 ÷ 25 = 2.7

So, 6.75 divided by 2.5 equals 2.7.

###### Fun Example: Multiplying and Dividing Decimals with a Shopping Theme 🛒

**Multiplying Prices**

Imagine you are buying 2.5 pounds of apples, and each pound costs $1.3. To find the total cost, you multiply:

2.5 pounds × $1.3 per pound = $3.25

So, the total cost is $3.25.

**Dividing the Bill**

After shopping, you and a friend decide to split the bill of $6.75 equally. To find out how much each person pays, you divide:

$6.75 ÷ 2 = $3.375

So, each person pays $3.375.
