Proportional quantities

What is greatness?

We understand by greatness all that can be measured, counted. The quantities may have their measurements increased or decreased.

Some examples of magnitude are: volume, mass, surface, length, capacity, speed, time, cost and production.

It is common in our day to day situations in which we relate two or more quantities. For example:

  • In a "kilometers against the clock" race, the higher the speed, the shorter the time spent on the race. Here the quantities are speed and time.
  • In a furnace used for the production of ordinary cast iron, the longer the use time, the greater the iron production. In this case, the quantities are time and production.
