What are the similarities to percent proportion and percent equation?

Both percent proportion and percent equation are methods used to solve problems involving percentages. The percent proportion expresses the relationship between the part, whole, and percent as a fraction: ( \frac{\text{part}}{\text{whole}} = \frac{\text{percent}}{100} ). The percent equation, on the other hand, is formulated as ( \text{part} = \text{percent} \times \text{whole} ). While they are different in form, both approaches ultimately help find the same values in percentage-related problems.
