RATIO AND PROPORTION - University of Saint Joseph

In general, y1 = k x1 and y2 = kx2 may represent two pairs of numbers that are in the same ratio and therefore form a proportion where x1 = y1. With a little algebra, we can . x2 y2. show that this proportion follows logically if y1 = k x1 and y2 = k x2 . Solve each of the last two equations for k: y1 = k x1 y2 = k x2. y1 = k y2 = k ................
