• 4 + 25/100 = 4 + 0.25 = 4.25
This interpretation treats "25" as a decimal part added to the whole number 4.

Converting 4/25 to a Percentage

Step-by-Step Conversion Process

Converting a fraction into a percentage involves the following steps: 1. Divide the numerator by the denominator to get a decimal. 2. Multiply the decimal by 100 to convert it to a percentage. 3. Add the percentage sign (%) to indicate the value. Applying this process to 4/25: 1. 4 ÷ 25 = 0.16 2. 0.16 × 100 = 16 3. Therefore, 4/25 = 16% Result: 4/25 as a percent is 16%.

Alternative Methods

While division and multiplication are straightforward, there are other ways to approach this conversion:
• Cross-multiplication: Set up a proportion:
\[ \frac{4}{25} = \frac{x}{100} \] Cross-multiplied: \[ 4 \times 100 = 25 \times x \] \[ 400 = 25x \] \[ x = \frac{400}{25} = 16 \] Confirming that 4/25 = 16%.
• Using decimal approximation: Recognize that 1/25 = 4%, so 4/25 = 4 × 4% = 16%.

Applications of Percentages in Real-Life Situations

Financial Contexts

Percentages are fundamental in finance for calculating interest rates, discounts, and investment returns.
