Question

the mean proportion between 3 and 12 is

Answer 1

Answer:

The mean proportion between 12 and 3 is 6.

Step-by-step explanation:

Let the mean proportion between 12 and 3 be a,

Hence, according to the properties of the ratio and proportion,

= >  12 / a = a / 3

= >  12 x 3 = a x a

= >  4 x 3 x 3= a^2

= >  6 x 6 = a^2

= >  6 = a

Therefore the mean proportion between 12 and 3 is 6.
