An example of a directly proportional relationship among the given sentences is The heavier the sofa, the more people that are needed to lift it.

• The analysis of direct proportion or a direct variation occurs when in a relationship, two quantities are used. And these two quantities' ratio always gives a constant value.

• Then the quantities are said to be directly proportional to each other. In mathematics, two proportional quantities are showcased by putting a symbol for proportion.
