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

69:3=(60+9):3=(60:3)+(9:3)=20+3=23

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

88:4=(80+8):4=80:4+8:4=20+2=22

84:2=(80+2):2=(80:2)+(4:2)=40+2=42

62:2=(60+2):2=(60:2)+(2:2)=30+1=31

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

80:2=(40+40):2=(40:2)+(40:2)=20+20=40

99:3=(90+9):3=(90:3)+(9:3)=30+3=33

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

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

b)

68:4=(40+28):4=(40:4)+(28:4)=10+7=17

56:2=(30+26):2=(30:2)+(26:2)=15+13=28

57:3=(30+27):3=(30:3)+(27:3)=10+7=17

42:3=(30+12):3=(30:3)+(12:3)=10+4=14

84:7=(70+14):7=(70:7)+(14:7)=10:2=12

96:8=(80+16):8=(80:8)+(16:8)=10+2=12

72:6=(60+12):6=(60:6)+(12:6)=10+2=12

65:5=(50+15):5=(50:5)+(15:5)=10+3=13

76:2=(50+26):2=(50:2)+(26:2)=25+13=38

75:3=(60+15):3=(60:3)+(15:3)=20+3=23

92:2=(70+22):2=(70:2)+(22:2)=35+11=46

81:3=(60+21):3=(60:3)+(21:3)=20+7=27

96:4=(80+16):4=(80:4)+(16:4)=20+4=24

32:2=(20+12):2=(20:2)+(12:2)=10+6=16

75:5=(50+25):5=(50:5)+(25:5)=10+5=15

72:3=(60+12):3=(60:3)+(12:3)=20+4=24

51:3=(30+21):3=(30:3)+(21:3)=10+7=17

85:5=(50+35):5=(50:5)+(35:5)=10+7=17
