Question

Show that 2,6,9,1 are in proportion or not.

Answer 1

$\underline \bold {Solution:-}$

The numbers the said to be in proportion of the product of there extreme is equal to the product of there mean.

Here, extreme are:- 2 and 1

So, the product of extreme = 2 × 1 = 2

And,

Mean are :- 6 and 9

So, the product of mean = 6 × 9 = 54

Since , Product of extreme ≠ Product of mean

So, they are not in proportion.

Answer 2

Answer:

We will check their proportion If thier product of extreme and mean are equal

Product of extreme = 2*1

= 1

Product if mean = 6*9

= 54

So they are not propotion to each other
