Question

how to make a chart on continued and mean proportional in A-4size sheet​

Answer 1

Answer:

Step-by-step explanation:

To answer this question, one should know what is proportion and what is mean proportional.

when four numbers say A,B,C,D are in similar quantities such that A:B= C:D then they are said to be in proportion.

when A,B,C are in continued proportion then B is said to be the mean proportional.

let us take A=9 and C=16 and B as X. then

A:X : : X:C

9:X : : X:16

{x}^{2} = 9 \times 16x2=9×16

{x}^{2} = 144x2=144

Therefore, x = 12.

So, the mean proportional of 9 and 16 is 12
