A ratio is a comparison of quantities having the same unit. Unit 1: Proportional relationships. Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate. Solve proportions by multiplying both sides of the equation by the product of the denominators, or cross multiply.
When \(e = 20\), \(p = 10\). The constant of proportionality has a compound unit, the unit of 𝑦 per unit of 𝑥, for example miles per gallon or pages per minute.
