Question

Efectueaza inpartirile, folosind descompunerea;24÷2=12;55÷5=11;36÷3=12;44÷2=22;68÷2=34;39÷3=13;96÷3=32;84÷4=21

Answer 1

24:2=12⇒12+12=24 iar prin inmultire 12 ori 2=24
36:3=12⇒12+12+12=36 iar prin inmultire 12 ori 3=36
68:2=34⇒34+34=68 iar prin inmultire 34 ori 2=68
39:3=13⇒13+13+13=39 iar prin inmultire 13 ori 3=39
96:3=32⇒32+32+32=96 iar prin inmultire 32 ori 3=96
84:4=21⇒21+21+21+21=84iar prin inmultire 21 ori 4=84

Answer 2

24:2=12
(20:2)+(4:2)
10+2=12

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

36:3=12
(30:3)+(6:3)
10+2=12

44:2=22
(40:2)+(4:2)
20+2=22

68:2=34
(60:2)+(8:2)
30+4=34

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


96:3=32
(90:3)+(6:3)
30+2=32

84:4=21
(80:4)+(4:4)
20+1=21
