- The whole amount matches with 100.
- Equivalent fractions can be used to rewrite a ratio as a percent.
- The numerator and denominator must be multiplied by the same factor to create an equivalent ratio.
✏️ Worked Examples
🧠 Math Vocabulary
- Percent: A rate or ratio per 100.
- Part: The amount being compared to the whole.
- Whole: The total amount.
- Equivalent Fraction: A fraction that represents the same value as another fraction.

💡 Main Idea
In this lesson, students learn how to find what percent one number is out of another by rewriting the part-to-whole ratio as an equivalent rate per 100. This connects fractions, ratio tables, and percent reasoning.
📚 What You Should Already Know
Students should understand fractions, equivalent fractions, ratios, and basic multiplication and division. It also helps to know that percent means “out of 100.”
🚀 What Comes Next
After finding percents using equivalent rates out of 100, students can solve percent word problems, use proportions, interpret ratio tables, and apply percent reasoning to discounts, tax, tips, and percent change.
