Answer:
The two numbers are 64 and 8. 
Step-by-step explanation:
You meant "quotient" of two numbers, right?
Represent the numbers by x and  y.
Then the quotient is x/y = 8, and beyond that we know that x + y = 72.
Solve this for x and y.  
If x/y = 8, then x = 8y.  Substituting this into x + y = 72, we get:
(8y) + y = 72, or 9y = 72.  Dividing both sides by 9 yields y = 8.
Since x/y = 8, letting y = 8 results in x = 64.
The two numbers are 64 and 8.
