Explanation

Let the two numbers be $x$ and $y$, where $x > y$.

We are given:

$$x+y=40\text{(1)}$$$$x - y = 4 quad text{(2)}$$

Adding equations (1) and (2):

2x=44⟹x=22

Subtracting equation (2) from (1)

$$2y = 36 implies y = 18$$

The numbers are 22 and 18.
The ratio of the numbers is:

x​/y=22​/18

=11/9​
