Question

check if 3 9 12 are in continued proportion​

Answer 1

Answer:

3,12 and x are in continued proportion then

3:12::12:x

3x=12×12

x=48

Answer 2

Answer:

Here's your Answer.

Step-by-step explanation:

If 3, 9 and 12 are in continued then $9^2$ should be equal to 12 x 3.

Therefore $9^2$ = 81. 12 x 3 = 36

81 is not equal to 36 and Hence 3, 9 and 12 are not in continued proportion.
