Answer:
Step-by-step explanation:
15 bags for $20 can be represented with 15/20 
so x bags for $4 can be represented with x/4 
now if you proportion it out (ricochet), 4x15 is 60, 60 divided by 20 is 3, so you can buy 3 bags of potatoes with $4. 
OR 
you could do 15/20 is 0.75
0.75 times 4 is 3, so $4 can buy you 3 bags. 
 
        
                    
             
        
        
        
3,205,008 = 3,000,000 + 200,000 + 5,000 + 8 in expanded form
3,205,008 = 3 million, 2 hundred and five thousand and eight in word form.
        
             
        
        
        
Answer:
2(n+1)+2
You start with two greens and two columns of two orange squares while adding two orange squares each time. So, the bolded part is the green squares that stay the same. The 2(n+1) represents the two orange columns that increase by one block on each side per image.
 
        
             
        
        
        
I don't speak Spanish but I think that this is what you meant:
80 * 2/5 = 32
so 2/5 of 80 % is 32 % (80/5 * 2)
