0.9/x = x/0.4
=> x^2 = 0.9 × 0.4 = 0.36
=> x = √0.36 = 0.6
HOPE IT HELPED
PLEASE MARK IT AS THE BRAINLIEST ANSWER
The mean proportional between 0.9 and 0.4 is 0.6.
Since we have given that
Let the mean proportional be 'x'
So, its proportion can be written as
So, it becomes,
Hence, the mean proportional between 0.9 and 0.4 is 0.6.
