We need to complete the table using equivalent ratios:
Let set x for the missing values:
Then, if they have the same ratio, we can equal both :
8/4 = x/6
Solve for x:
6*8/4 = x
Then x = 12
The first blank space is 12.
Now, for the second black space:
12/6 = 10/x
Solve for x:
x= 10* (12/6)
x= 5
The second black space is 5.
