28. Решите примеры.

Решение:

1. 
   

   \( 16 : 2 + 135 = 8 + 135 = 143 \)

   
   

   \( 0.5 + 49 = 49.5 \)

   
   

   \( 1 \cdot 26 - 19 = 26 - 19 = 7 \)

   
   

   \( 20 \cdot 3 + 37 = 60 + 37 = 97 \)

   
   

   \( 80 : 10 + 371 = 8 + 371 = 379 \)

   
   

   \( 9 \cdot 10 - 27 = 90 - 27 = 63 \)

   
   


2. 
   

   \( 24 : 1 + 357 = 24 + 357 = 381 \)

   
   

   \( 180 : 9 \cdot 0 = 20 \cdot 0 = 0 \)

   
   

   \( 7 \cdot 10 + 70 = 70 + 70 = 140 \)

   
   

   \( 6 \cdot 0 + 100 = 0 + 100 = 100 \)

   
   

   \( 0 : 6 + 500 = 0 + 500 = 500 \)

   
   

   \( 42 \cdot 1 - 42 = 42 - 42 = 0 \)

   
   

Ответ: 1) 143, 49.5, 7, 97, 379, 63; 2) 381, 0, 140, 100, 500, 0.
