PERCENTAGE OF A NUMBER

To calculate a percentage of a number, follow these steps:

1. Convert the Percentage to a Decimal: Divide the percentage by 100. For example, 25% becomes 0.25.

2. Multiply by the Number: Multiply the decimal by the number to find the percentage value.

Formula:

$\text{Percentage of a Number} = \left(\frac{\text{Percentage}}{100}\right) \times \text{Number}$

Example Calculation:

• Find 20% of 150:
  1. Convert 20% to a decimal: $20 \div 100 = 0.20$
  2. Multiply by 150: $0.20 \times 150 = 30$

So, 20% of 150 is 30.
