Set the given numbers in such a way that the ratio of first two numbers is equal to the ratio of other two numbers
12:16 = 3:4
And 30:40 = 3:4
The ratio is same so they are in proportion....
12 : 16 :: 30 : 40
This is the required proportion
12:16 = 3:4
And 30:40 = 3:4
The ratio is same so they are in proportion....
12 : 16 :: 30 : 40
This is the required proportion
