Answer:

-27 and -33.

Explanation:

If the number have 9:11 of ratio, this can be expressed like this:
(x)/(y) =(9)/(11). Because a ratio represents a equivalence between two fractions.

The problem says that their difference is 6, which can be expressed like:
x-y=6

Where x and y are the unknown numbers.

So:
x=6+y; we replace this equation in the ratios one.


(x)/(y) =(9)/(11) \\(6+y)/(y) =(9)/(11) \\66+11y=9y\\66=9y-11y\\66=-2y\\(66)/(-2)=y\\ y= -33.

To calculate the second number we use:
x-y=6\\x=6+y\\x=6+(-33)\\x=6-33\\x=-27

Hence, the two numbers that fit with the 9:11 ratio and their difference of 6 are -33 and -27.
