Question

Verify whether the following numbers are in proportion: 1.5, 4.5, 2, 6

Answer 1

1.5:4.5=2:6

15/45=2/6

1/3=1/3


lhs=rhs


hence,the numbers are in proportion

Answer 2

$\underline \bold {Solution:-}$

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

Here, extreme are:- 1.5 and 6

product of extreme = 1.5 × 6 = 9

Mean are :- 4.5 and 2

product of mean = 4.5 × 2 = 9

Since , Product of extreme= Product of mean

So, they are in proportion.
