Question

Show that 1.5,4.5,1,6 are not in proportion

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:- 1.5 and 6

So, the product of extreme = 1.5 × 6 = 9

And,

Mean are :- 4.5 and 1

So, the product of mean = 4.5 × 1 = 4.5

Since , Product of extreme ≠ Product of mean

So, they are not in proportion.

Answer 2

1.5×1=1.5

4.5×6=25.0

We know that:-

They are not proportional of wach other

so they are not propotion
