Urgent!!!!!!!!!!!!!!!!!!!! va rog​

Answer 1

Explicație pas cu pas:

a. 462 x 999 = 462 x (1000 - 1)

= 462 x 1000 - 462 x 1

= 462000 - 462

= 461538

b. 328 x 999 = 328 x (1000 - 1)

= 328 x 1000 - 328 x 1

= 328000 - 328

= 327672

c. 478 x 999 = 478 x (1000 - 1)

= 478 x 1000 - 478 x 1

= 478000 - 478

= 477522

                     

Answer 2

Răspuns:

462×999=462×(1000-1)=

=462×1000-462×1=

=462000-462=461538

328×999=328×(1000-1)

=328×1000-328×1=

=328000-328=327672

478×999=478×(1000-1)

=478×1000-478×1=

=478000-478=477522
