Question

What is the mean proportion between 1/8 and 1/18​

Answer 1

Answer:

Solution: To find the mean proportional between 8 and 18, first multiply the two given numbers together, then find the square root out of their product.

Then the answer will be the mean proportional between 8 and 18.

Here, 8 x 18 = 144 V144 = 12

So, 12 is the mean proportional between 8 and 18.

Answer 2

$\huge\fbox\red{❥answer}$

To find the mean proportion between 1/8 and 1/18, first multiply the two given numbers togethers, then find the square root of their product. Then the answer will be the mean proportional between 1/8 and 1/18.

$\rm{}here, \: \frac{1}{8} \times \frac{1}{18} = \frac{1}{144} \\ \\ \implies \: \sqrt{ \frac{1}{144} } = \frac{1}{12}$

So, 1/12 is the mean proportion between 1/8 and 1/18
