 2: Distribution 
 3: Subtraction
 4: subtraction 
  5:division 
Step-by-step explanation:
 
        
             
        
        
        
Divide both sides by their LCD, 2
2/4 = 1/2
1/2 is irreducible 
        
             
        
        
        
X=2 shown in the work below.

For quarters we have:
 
 Where,
 x: number of quarters
 Clearing x we have:
 
 For nickels we have:

 Where,
 y: number of nickels
 Clearing y we have:
 
 Then, the ratio of quarters to nickels is:
 
 Simplifying we have:

 Answer:
 The ratio of quarters to nickels in a dollar is:
