Step-by-step explanation:
Given:-
The numbers are 12, 15, 16, 20
To find:-
Check whether the given numbers, 12, 15, 16, 20 are in proportion or not.
Solution:-
Given numbers are 12, 15, 16, 20
Extremes = 12 and 20
Means = 15 and 16
Product of means = 15×16 = 240
Product of extremes = 12×20 = 240
Product of means = Product of extremes
We know that
In proportion,
Product of means = Product of extremes
So, Given numbers are in proportion
