Answer 1

4) 
1)
a = 3 x b = 3 x 74 = 222
b = c : 9 = 666 : 9 = 74
c = 2 x d = 2 x 333 = 666
d = e : 3 = 999 : 3 = 333
e = 999 → cel mai mare numar ntural de 3 cifre

Verific: 999 : 3 x 2 : 9 x 3= 333 x 2 : 9 x 3 = 666 : 9 x 3 = 74 x 3 = 222

2) 
a = 2 x b = 2 x 342 = 684
b = c : 3 = 1 026 : 3 = 342
c = 6 x d = 6 x 171 = 1 026
d = e : 2 = 342 : 2 = 171 
e = 3 x 114 = 342

Verific:  3 x 114 : 2 x 6 : 3 x 2 = 342 : 2 x 6 : 3 x 2 = 171 x 6 : 3 x 2 =
=  1 026 : 3 x 2 = 342 x 2 = 648
