Converting a decimal to another form can often be confusing, but it’s essential to understand. A decimal is a way of representing fractions in a base-10 system, which is very common in math and everyday use. When you convert from a decimal to a percentage, you're effectively changing the way the number is expressed without changing its value.
For example, when you have a decimal like 1.395, you can think of it in terms of its place value. Each digit to the right of the decimal point represents a fraction of ten, hundred, or thousand and so on.
The conversion itself involves a simple multiplication by 100 to change it into a percent form. This doesn't alter the value but rather signifies how much the decimal represents out of 100.
Understanding this core idea is crucial for tackling more complex problems related to percentages and decimals.

Calculating percentages from decimals is straightforward with some consistent steps. When you see a decimal, remember that 'percent' means 'per hundred.' Thus, converting from a decimal to a percent involves multiplying by 100.
The main reason for this multiplication is that it scales the decimal up by a factor of 100, situating it within a more familiar context of percent values.
Consider the example 1.395 from our exercise. To convert it to a percentage, you multiply it by 100: \[ 1.395 \times 100 = 139.5 \]
This tells us that the decimal 1.395 is equivalent to 139.5 percent. Always remember to include the '%' symbol after your calculation to indicate that your number is a percentage.
This simple multiplication aligns the decimal with a base of 100, enabling a more intuitive understanding of its value.

Understanding the mathematical steps in converting a decimal to a percent can demystify the process. Let’s break it down into clear, manageable steps:

• Step 1: Start with your decimal number. For instance, 1.395.
• Step 2: Multiply this number by 100. Essentially, you are determining how many parts out of 100 the decimal represents. For 1.395: \[ 1.395 \times 100 = 139.5 \]
• Step 3: Attach the percent symbol (%) to the result to signify that the number is now in percent form. So, 1.395 becomes 139.5%.

These steps ensure that you correctly convert any decimal to a percent. Consistently applying this method will help you in various math problems and real-life scenarios related to percentages.
Getting comfortable with this process also strengthens your overall math skills, making it easier to handle different types of numerical conversions.
