Understanding Percentage Calculations

A percentage is a fraction of 100. When we say "20%", we mean 20 out of 100, or 20/100. To find a percentage of a number, we multiply the number by the percentage expressed as a decimal.

While the above method is the most straightforward, there are other ways to approach this problem:

• Fraction Method: 20% can be expressed as the fraction 20/100, which simplifies to 1/5. Multiplying $20.00 by 1/5 (or dividing by 5) also gives you $4.00.

• Mental Math: Since 20% is one-fifth, you can quickly calculate one-fifth of $20.00 by dividing $20.00 by 5. This is a useful technique for simpler percentage calculations.
