"Direct Proportion" Proportional PPT courseware

The time and distance traveled by a car are as follows.

Observe the table above and answer the following questions:

(1) What two quantities are in the table?

(2) How does the distance change over time?

(3) What is the corresponding ratio of distance to time? What is the ratio?

The ratio of distance to time:

(1) The distance changes with time;

(2) As time expands, the distance will also expand; as time shrinks, the distance will also shrink;

(3) The ratio of distance to time is 90.

Two related quantities. If one quantity changes, the other quantity will also change. If the ratio (that is, the quotient) of the two corresponding numbers in the two quantities is constant, the two quantities are said to be directly proportional. quantities, their relationship is called a direct proportional relationship.
