Proportional relationships (e.g. speed as the ratio of distance traveled to time taken) among different types of quantities provide information about the magnitude of properties and processes.

TERMS

  • Quantities - the amount (or number) of a thing

  • Proportional relationship - relation of one dataset to another dataset

    • Directly - two quantities are proportional to each other (linear proportion)

    • Inversely - as one quantity increases the other decreases. Product of values is constant.

  • Magnitude - the size, scale or importance of properties and processes
