20/45 for blue
        
             
        
        
        
I think your answer is 1,800
The sum of these numbers is 1771, so if you round up or down, whichever is closest, then you would get a total of 1,800. 
I hope this helps!
        
                    
             
        
        
        
Answer:
126 apples
Step-by-step explanation:
Let the number of apples picked by Mary=m
Cindy picks 6 times as many as Mary= 6Xm=6m
John picks 8 times as many as Mary= 8Xm=8m
Altogether they picked a total of 135 apples.
m+6m+8m=135
15m=135
m=135/15
m=9
We want to determine how many apples John and Cindy Picked.
John Picked 6m apples
Cindy Picked 8m apples
Their combined total= 6m+8m =14m 
Since m=9
14m =14 X9 =126 apples
John and Cindy picked a total of 126 apples
 
        
             
        
        
        
189 because you have to multiply by 3 twice.
