Understanding how to convert percentages to decimals is a fundamental math skill. Percentages are an essential part of everyday math, especially when dealing with discounts, interest rates, or scores. Typically, a percentage represents a part out of 100. For example, 6% is 6 parts out of 100 parts.
To convert a percentage to a decimal, you need to divide the percentage value by 100. This is because percent literally means 'per hundred.' So, for the given exercise, 6% becomes \( \frac{6}{100} = 0.06 \).
This step is crucial since calculations in mathematics, especially multiplication and division, are often done more easily with decimals than with percentages.

Basic arithmetic involves the four fundamental operations of addition, subtraction, multiplication, and division. These operations are the building blocks of more complex math. In the exercise, multiplication is the operation used. When you calculated 6% of 20, you applied multiplication on the decimal representation of the percentage.
To do the calculation, the decimal 0.06 is multiplied by 20. Multiplication like this can be done by simple steps—first multiply as if there are no decimals, and then count the decimal places in the original numbers to place the decimal point correctly in the answer. Here, 0.06 times 20 gives us \( 0.06 \times 20 = 1.2 \). As you continue with mathematical problems, becoming comfortable with multiplication and other operations will help with understanding and solving more complex questions.

Approaching mathematical problems with a structured plan ensures clarity and accuracy. The original exercise is a classic example of a percentage calculation problem, where converting percentages to decimals and performing arithmetic operations are involved.
To solve such problems effectively:

• Identify what needs to be converted (like percentage to decimal).
• Understand the operation required (in this case, multiplication).
• Perform the operation step by step to reach the solution.

Encouraging a methodical approach can reduce mistakes and improve understanding. Solving mathematical problems incrementally, and double-checking each step can greatly enhance problem-solving skills. Trying similar problems repeatedly can also build a strong foundation and confidence in handling more challenging math exercises.
