Answer:
the ratio of the third proportional to 12 and 30 is 2:5
Step-by-step explanation:
Let the third proportional to 12 and 30 be x.
Then, 12 : 30 :: 30 : x <=> 12x = 30 x 30 <=> x = (30*30\12)
= 75.
Third proportional to 12 and 30 = 75.
Mean proportional between 9 and 25 = sqrt(9)*sqrt(25)
= 15.
Required ratio = 75 : 15 = 5 : 1.
