How to calculate 8 x 0.4

Multiplying 8 by 0.4 is a basic arithmetic operation that can be performed using simple multiplication rules. Here's how to do it:

Multiplication Formula

The basic formula for multiplication is:

a × b = product

Where:

a is the first number (8 in this case)
b is the second number (0.4 in this case)
product is the result of the multiplication

Step-by-step calculation

Write down the numbers vertically:
```
   8.0
×  0.4
```
Multiply 4 (the last digit of 0.4) by 8:
```
   8.0
×  0.4
-------
    32.0
```
4 × 8 = 32, and we place the decimal point to match the original numbers.
The result is 3.2, which is the product of 8 multiplied by 0.4.

Decimal Multiplication Tip

When multiplying decimals, it's helpful to first multiply the numbers as if they were whole numbers, then place the decimal point in the final product so that it has the same number of decimal places as the original numbers combined.
