1. Identify the Decimal Value: Begin with the decimal number that you wish to convert to a percentage. For example, consider the decimal 0.85.
2. Multiply by 100: To convert a decimal to a percentage, multiply the decimal by 100. For the example of 0.85, the calculation would be:0.85×100=850.85 \times 100 = 850.85×100=85
3. Add the Percentage Symbol: Once the multiplication is complete, the result is the percentage. In this case, 0.85 as a percentage is 85%.Thus, 0.85 is equivalent to 85%.

Example Conversion

Let’s go through a few more examples:

• Decimal: 0.25
  Conversion: 0.25×100=25%0.25 \times 100 = 25\% 0.25×100=25%
• Decimal: 1.5
  Conversion: 1.5×100=150%1.5 \times 100 = 150\% 1.5×100=150%
• Decimal: 0.03
  Conversion: 0.03×100=3%0.03 \times 100 = 3\% 0.03×100=3%

These examples show how decimals are multiplied by 100 to obtain their percentage form.
