Question

afla numerele a;b,c,stiind că:a)a+b+c=111*10.;a+b=11*10.,b+c=11*100.;b)a+b+c=333×10;a+b=33×10;b+c=33×100

Answer 1

a)   a + b + c = 111 × 10

a + b + c = 1 110

a + b       =   110

     b + c = 1 100

____________

1 110 - 1 100 = 10 ( a )

110 - 10 = 100 ( b )

1 100 - 100 = 1 000 ( c )

________________________________________________________

b)    a + b + c = 333 x 10

a + b + c = 3 330

a + b       =   330

     b + c =3 300

_______________

3 330 -  3 300 = 30 ( a )

   330 -     30 = 300 ( b )

3 300 - 300 = 3 000 ( c )

Answer 2

SUCCES!!!
