Key Concepts

What is a Percent?

Definition: The term "percent" means "per hundred." It represents a fraction of 100.

Example:

  • 25% means 25 per 100.
  • 75% means 75 per 100.

What is a Decimal?

Definition: A decimal is a way of expressing numbers that are not whole, using a decimal point to separate the whole number from the fractional part.

Example:

2.05 has a decimal point between the 2 and the 0.

36 can be written as 36.0 or 36.000, where the decimal point is followed by zeros, indicating no fractional part.

Steps to Convert a Percent to a Decimal

Converting a percentage to a decimal involves a simple two-step process:

  1. Remove the Percentage Symbol (%):
    Simply eliminate the "%" sign from the number.

  2. Move the Decimal Point Two Places to the Left:
    Shift the decimal point two places left to convert the percentage into a decimal. If the number doesn't have a decimal point, assume it to be at the end of the number (e.g., 36% becomes 36.0).

25% 25 0.25 0.25
75% 75 0.75 0.75
8% 8 0.08 0.08
4.6% 4.6 0.046 0.046

Detailed Examples

Example 1: Converting 13% to a Decimal

  1. Remove the % symbol:
    13% becomes 13.

  2. Move the decimal point two places to the left:
    Since 13 is a whole number, the decimal point is assumed to be at the end: 13.0.
    Move the decimal two places left: 0.13.

  3. Final answer:
    13% = 0.13

Note: The zero after the decimal point is essential for maintaining the decimal's place value but can be omitted for simplicity if preferred (e.g., 0.13).

Example 2: Converting 68% to a Decimal

  1. Remove the % symbol:
    68% becomes 68.

  2. Move the decimal point two places to the left:
    Since 68 is a whole number, the decimal point is assumed to be at the end: 68.0.
    Move the decimal two places left: 0.68.

  3. Final answer:
    68% = 0.68

Example 3: Converting 8% to a Decimal

  1. Remove the % symbol:
     8% becomes 8.

  2. Adjust the number for decimal movement:
    To move the decimal two places left, add two zeros before the 8: 008.
    This ensures clarity in decimal placement.

  3. Move the decimal point two places to the left:
    8% = 0.08

  4. Final answer
    8% = 0.08

Note: Adding a zero before the number does not change its value but helps in correctly placing the decimal point.

Example 4: Converting 4.6% to a Decimal

  1. Remove the % symbol:
     4.6% becomes 4.6.

  2. Adjust the number for decimal movement:
    To move the decimal two places left, add two zeros before the 4.6: 004.6
    This ensures clarity in decimal placement.

  3. Move the decimal point two places to the left:
    4.6% = 0.046

  4. Final answer
    4.6% = 0.046
