Question

Show that 1.5,4.5,1,3 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 3

So, the product of extreme = 1.5 × 3 = 4.5

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 in proportion.

Answer 2

From the above question , taking product of extreme and product of mean

✏✏✏1.5×1=1.5

✏✏✏4.5×3=13.5

We can conclude from given proportion

that :-

They had not same no so that we can cancel them or they are not propotion
