Explanation:
We want a number between 4 1/5 and 4.25.  We will convert 4 1/5 to a decimal first:
Divide 1 by 5:  1/5 = 0.2.
This makes 4 1/5 = 4 + 1/5 = 4 + 0.2 = 4.2.
We want a number between 4.2, which can be written as 4.20, and 4.25.  Any number between will do, so the possible answers would be 
4.21, 4.22, 4.23, or 4.24.<u />
        
                    
             
        
        
        
Answer:
D
Step-by-step explanation:

 < 12
 < 12
Multiply both sides by 4 to clear the fraction
j < 48 → D
