Question

find the mean proportion of the following 5, 20​

Answer 1

$\longrightarrow\huge\underline \mathfrak {solution}$

the mean proportional, or geometric mean, is always written in the following format: 

a/x = x/r, where a and r are two different numbers. 

so the mean proportion of 5 and 20 is 

5/x = x/20. just cross multiply and get 100 = x^2, which makes x = 10. 1

10 is the mean proportional.
