Question

find the mean proportion of 27 and 243 for 6th class​

Answer 1

Answer:

81

Step-by-step explanation:

Let the mean proportion between 27 and 243 be x.

•°• 27 : x :: x : 243

27/x = x/243

x × x = 243 × 27

x² = 6561

x = √6561

x = 81

Hence, the mean proportion between 27 and 243 is 81.
