Use Pemdas
                                
             
                    
              
Answer: First, I would round all numbers (to the nearest tenth). 
183 rounds to 180 
76 rounds to 80 
15 rounds to 20 
29 rounds to 30. 
Now plug those numbers into the equation. 
180/(80-20)+30 
Using PEMDAS, I solve the parentheseis first. 
80-20=60. 
180/60+30 
Then, add 60+30. 
60+30=90. 
you get 180/90. 
180/90=2.
