We use cross product. To find cross product of proportion we use product of extreme term and mean term
30:40::45:60
30×60= 40×45
1800= 1800
They are in proportion

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:- 30 and 60
So, the product of extreme = 30 × 60 = 1800
And,
Mean are :- 40 and 45
So, the product of mean = 40 × 45 = 1800
Since , Product of extreme = Product of mean
So, they are in proportion.
