Equations for proportional relationships

Understand a proportion as two equivalent ratios written as an equation. Write a proportion of two equivalent ratios. Attend to precision with units when setting up a proportion (MP.6). Solve a proportion using the relationship across the numerators, the relationship between the numerator and the denominator, or cross multiplication.

Equations for proportional relationships. When two quantities x and y are in a proportional relationship, we can write the equation y = kx and say, “ y is proportional to x .”. In this case, the number k is the corresponding constant of proportionality. We can also write the equation x = 1 ky and say, “ x is proportional to y .”.
