"Proportional Quantities" Direct Proportional and Inverse Proportional PPT Courseware

Volume changes with height. We call two quantities like this related quantities.

As the height increases, the volume expands.

The height decreases and the volume decreases.

Volume/height=base area

Two quantities, if one quantity changes, the other quantity will also change, and the ratio (that is, the quotient) of the two quantities is constant. The two quantities are called directly proportional quantities, and their relationship is called a direct proportional relationship.

If the letters x and y are used to represent two related quantities, and k is used to represent their ratio (certain), the proportional relationship can be expressed by the following formula: y/x=k

Measure to judge:

To determine whether two quantities are directly proportional, it mainly depends on whether their quotient is certain.

(1) Write the ratios of several sets of distances and corresponding times, and compare the ratios. Let’s talk about what this ratio means.

(2) Are the distances in the table proportional to the time? Why?

(3) Draw the points representing the distance and corresponding time on the picture, and then connect them in order. And estimate how long it will take to drive 120km.

The width of a rectangle is constant, its length equals its area.
