Three Ways to Show Parts of a Whole

Fractions, decimals, and percents are different ways to describe the same thing: pieces of a whole.

Converting Between Forms

• Fraction to Decimal: Divide the numerator by the denominator (\( \frac{1}{4} = 0.25 \)).
• Decimal to Percent: Multiply by 100 (\( 0.25 \times 100 = 25% \)).
• Percent to Fraction: Write the percent over 100 and simplify (\( 25% = \frac{25}{100} = \frac{1}{4} \)).

Operations

Add, subtract, multiply, and divide fractions and decimals by finding common denominators or aligning decimal points.
