It's a trick question. There are an infinite number of mixed numbers between 3 and 4 that can multiply to equal 12 (for example, 3 and 3/7 times 3 and 1/2), but there are no mixed numbers between 3 and 4 that can multiply to equal 9. 3 times 3 is not between them but is 3, but that quantity is excluded because 3<x<4. Anything even a small bit above the number 3 would have to be multiplied by 2 and some fraction, which would not be between 3 and 4.
        
             
        
        
        
Answer:
8 = r
Step-by-step explanation:
 69 = 9r -3
Add 3 to each side
 69+3 = 9r -3+3
72 = 9r
Divide each side by 9
72 / 9 = 9r/9
8 = r

Prove that Dexter is wrong
To prove that Dexter is wrong, we use the following numbers.

The factors are:

3 factors
Using a greater number:

The factors are:

2 factors
From the above analysis:
4 has 3 factors and 5 has 2 factors; which shows that 5 has fewer factors
This shows that Dexter is wrong
