8 = 4w/3
  8 = 4w/3 
×3 = 4w×3
  24= 4w           ( the two 3s cross each other out)
÷4 = ÷4
  8 = w              ( the two 4s cross each other out)
        
             
        
        
        
Answer:
9
Step-by-step explanation:
Create a proportion

84 divide by what gives you 12? 7
So divide 63 by 7, and you get 9.
This doesn't work with all of these problems so you can always cross multiply then divide.
12(63) = 756
84(x) = 84x
84x = 756
84x/84 = 756/84
x = 9
