Answer:
No, not correct.  
Step-by-step explanation:
Note that 8 * 4.3 can be broken up as follows:
8 * (4 + 0.3)
and that 4*8 =32, and that 0.3(8) = 2.4 (not 0.24).
Then 8 * (4 + 0.3) becomes 32 + 2.4 = 34.4
 
        
             
        
        
        
Putting the two numbers together in fraction form of a ratio, we have 76/19. We know that something multiplied by 19 will equal to 76. 
When we try to multiply 4 and 19 together, we have our nice answer 76. We then replace out values in the original ratio, in which we get the final answer of 4:1, 4/1, or 4 to 1.
        
             
        
        
        
Answer:
4
Step-by-step explanation:
If two variables are proportional then
 
 ...(i)
    ...(i)
where, k is constant of proportionality.
The given equation is
 ...(ii)
       ...(ii)
where,
s = number of cups of seltzer.
c = cups of cranberry juice.
On comparing (i) and (ii), we get
Independent variable:  
Dependent variable:  
Constant of proportionality:  
Therefore, the constant of proportionality is 4.
