The complete statement is: 3 cups is to 9 cans as 6 cups is to 18 cans.
Completing the statement about these quantities.
From the question, we have the following parameters that can be used in our computation:
The table of values
Where, we have that the table is a proportional relationship
So, the constant of proportion is
k = 9/3
Evaluate
k = 3
using the above as a guide, we have the following:
Missing value = 18/3
Evaluate
Missing value = 6
Hence, the missing value in the statement is 6
