Question

REPREZINTA NUMARUL 8 CA: A)UN PRODUS DE 2 FACTORE,B)UN CIT A 2 NUMERE, C)JUMATATEA A UNUI NUMA . a :2=9 b:6=2 a+24=51 13+b=25 a-87=100 40-b=22.

Answer 1

1) a)4×2=8
b)40:5=8
c) 16:3=8

2)
a:2=9
a=2×9
a=18

b:6=2
b=6×2
b=12

a+24=51
a=51-24
a=27

13+b=25
b=25-13
b= 12

a-87=100
a=100+87
a=187

40-b=22
b=40-22
b= 18

Answer 2

a) 8 → produs de 2 factori
8 = 2 × 4
8 = 4 × 2
8 = 1× 8

b) 8 → catul a doua numere
8 = 24 : 3
8 = 16 : 2
8 = 32 : 4 
8 = 40 : 5

c) 8 → jumatatea unui numar
8 = 16 : 2

a : 2 = 9
a = 9 × 2
a =18

b : 6 = 2
b = 2 × 6
 b = 12

a+24=51
a= 51 - 24
a = 27

 13+b=25
b = 25 - 13
b = 12

 a-87=100
a = 100 + 87
a = 187

40-b=22
b = 40 - 22
b = 18
