In this problem, the word is excessive.
Mentioning that the numbers are fractions, is excessive, too.
The correct formulation is THIS :
The difference of two numbers is one third of their sum.
Find the ratio of the larger number to the smaller one.
In this formulation, the solution is as follows.
Let x be the greater number, while "y" be the smaller number.
Then the condition says
x - y = .
Multiply both sides by 3 and simplify
3x - 3y = x + y.
3x - x = 3y + y
2x = 4y
It implies
= = 2.
ANSWER. Under the given conditions, the ratio of the larger number to the smaller is 2.
Solved.
The post-solution note:
The numbers can be rational, irrational, algebraic, transcendent, and even complex.
The statement remains true in all these cases.
