Question

find the the mean proportion between g and 16​

Answer 1

what do you mean? cannot understand

Answer 2

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

Therefore, x = 12.
