Alege procedeul potrivit pentru a calcula.
___________________________________________
a) ( 14 + 23 + 13 ) : 5 =
( 37 + 13 ) : 5 =
50 : 5 = 10
_______________________
b) ( 12 + 26 + 25 ) : 7 =
( 38 + 25 ) : 7 =
63 : 7 = 9
_______________________
c) ( 35 + 27 + 10 ) : 8 =
( 62 + 10 ) : 8 =
72 : 8 = 9
