Multiplying Decimals by Whole Numbers
Multiplying a decimal by a whole number is a straightforward process. Here's how it works:

Ignore the decimal point: Initially, pretend the decimal point isn't there. So, we're essentially multiplying 3 by 10.

Multiply the whole numbers: 3 x 10 = 30

Place the decimal point: Now, count the number of decimal places in the original decimal number (0.3 has one decimal place). Place the decimal point in the answer so that it has the same number of decimal places. So, the answer is 3.0.
Therefore, 0.3 x 10 = 3.0
Simplifying the Answer
You can simplify the answer by removing the trailing zero. So, 3.0 is equivalent to 3.
Visualizing the Multiplication
Imagine you have 0.3 of a pie. Multiplying by 10 means you have 10 of these pieces of pie. In total, you have 3 whole pies.
Key Points to Remember
 Multiplying a decimal by a whole number greater than 1 will result in a larger number.
 When multiplying by 10, simply move the decimal point one place to the right.
 You can simplify the answer by removing trailing zeros.
