Question

Let's discuss.
Direct proportion
ZAN711
In the previous class we have learnt how to compare two numbers and write them
in the form of a ratio.
Example Look at the picture below. We see divisions of a circle made by its diameters.
(A)
(B)
(C)
(D)
Do you see any relationship between the number of diameters and the number of
divisions they give rise to?
In figure (A) one diameter makes
parts of the circle
In figure (B) two diameters make
parts of the circle.
In figure (D) four diameters make
parts of the circle.
No. of diameters
1 2 3
Here, the ratio of the number of diameters
No. of divisions
6 8
to the number of divisions remains constant.
