The question of two numbers is eight the sum of the same two numbers is 72 what are the two numbers
Otrada [13]

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.
