Explicație pas cu pas:

24 : 4 = ( 20 + 4 ) : 4 = 20 : 4 + 4 : 4 = 5 + 1 = 6

18 : 2 = ( 10 + 8 ) : 2 = 10 : 2 + 8 : 2 = 5 + 4 = 9

33 : 3 = ( 30 + 3 ) : 3 = 30 : 3 + 3 : 3 = 10 + 1 = 11

55 : 5 = ( 50 + 5 ) : 5 = 50 : 5 + 5 : 5 = 10 + 1 = 11

39 : 3 = ( 30 + 9 ) : 3 = 30 : 3 + 9 : 3 = 10 + 3 = 13

48 : 4 = ( 40 + 8 ) : 4 = 40 : 4 + 8 : 4 = 10 + 2 = 12
