Main Learning Objective:
Understand how to translate, formulate, and solve percentage problems using equations and equivalent fraction/decimal conversions.
Key Takeaways:
- Recognize that different verbal expressions of percentage problems often represent the exact same algebraic relation.
- Convert percentages to decimals by dropping the percent sign and shifting the decimal point two places to the left.
- Formulate simple linear equations to solve for unknown parts, percents, or wholes (e.g., 60p = 12 or 0.20n = 24).
- Memorize key common fraction-decimal-percent equivalencies (such as 1/8 = 0.125 = 12.5% and 2/3 ≈ 66 2/3%) for quick calculation.
