Question

find the mean proportional between
9and 1/36 with
explanation ​

Answer 1

Answer:

Step-by-step explanation:

that will be in proportion because 36/4 = 9               therefore it is 1/4 of 36 therefore it is in proportion.

Answer 2

Answer:

mean proportional is 325\72

Step-by-step explanation:

Question:-

Find the mean proportional between

9 and 1/36

$\huge\mathtt\pink{Solution:-}$

As we know ,

Mean of proportions=$\frac{sum\:of \:proportions}{number \:of\: proportion}$

here it is given that,

proportions=9 and 1/36

number of proportions=2

by using the formula we get

$\mapsto\:\frac{ 9+\frac{1}{36}}{2}$

so denominators are different so we need to take lcm

lcm=36

$\mapsto\: \frac{(\frac{324}{36} +\frac{1}{36)} }{2}$

$\mapsto\: \frac{\frac{325}{36} }{2}$

$\mapsto\: \frac{325}{2*36}$

$\mapsto\: \frac{325}{72}$

therefore the mean proportional of 9 and 1\36 is 325\72 .
