Answer 1

8)a/---/

b/---/+1/

c/---/+1/+1/

Ca sa aflam numerele facem:

21-3(1×3)=18

18:3(segmente egale)=6(un segment)

a=6

b=6+1=7

c=6+1+1=8

V:6+7+8=21

______________________________

9)a-b=24

a+b=90

a/---/

b/---/+24/

Ca sa aflam numerele facem:

90-24=66(doua segmente egale)

66:2(segmentele egale)=33(un segment)

a=33

b=33+24=57

V:57-33=24

57+33=90

11)l/---/---/

ll/---/---/+3/

lll/---/

Ca sa aflam numerele facem:

103-3=100(5 segmente egale)

100:5=20(un segment)

I=40

Il=43

Ill=20

V:43+40+20=103

Sper ca te-am ajutat!!
