\(7\frac{4}{13} - 4\frac{4}{13}\) : 0,15 - 4 : \(13\frac{6}{13} + 11\frac{7}{13}\)

Решение:

1. 
   
   7\(\frac{4}{13}\) = \(\frac{95}{13}\)
   
   


2. 
   
   4\(\frac{4}{13}\) = \(\frac{56}{13}\)
   
   


3. 
   
   \(\frac{95}{13}\) - \(\frac{56}{13}\) = \(\frac{39}{13}\) = 3
   
   


4. 
   
   3 : 0.15 = 20
   
   


5. 
   
   13\(\frac{6}{13}\) = \(\frac{175}{13}\)
   
   


6. 
   
   11\(\frac{7}{13}\) = \(\frac{150}{13}\)
   
   


7. 
   
   \(\frac{175}{13}\) + \(\frac{150}{13}\) = \(\frac{325}{13}\) = 25
   
   


8. 
   
   4 : 25 = 0.16
   
   


9. 
   
   20 - 0.16 = 19.84
   
   

Ответ: 19.84
