Answer:
9 cups
Step-by-step explanation:
We can write a ratio to solve
5 cups                     x cups
------------            = ----------------
80 cookies            144 cookies
Using cross products
5 * 144 = 80x
720 = 80x
Divide by 80
720/80 = 80x/80
9=x
 
        
                    
             
        
        
        
Answer:
In order to be called a 'rational' number, a number must be the quotient that results when one non-zero integer is divided by another. An irrational number can be written as a decimal, but not as a fraction. Your number is (3 sqrt(2)) / sqrt(2) = 3, and is a rational number indeed.
