Answer 1

C1:

72,54-(30,5+14,04)

=72,54-44,54

=28

C2:

72,54-(30,5+14,04)

=72,54-30,5-14,04

=42,04-14,04

=28

ai k mình mình k lại

Answer 2

C1: 72,54 - (30,5 + 14,04)

= 72,54 - 44,54

= 28

C2: 72,54 - (30,5 + 14,04)

= 72,54 - 30,5 - 14,04

= 42,04 - 14,04

= 28

Answer 3

Cách 1 :

   72,54 - ( 30,5 + 14,04 )

= 72,54 - 44,54

= 28

Cách 2

   72,54 - ( 30,5 + 14,04 )

= 72,54 - 30,5 - 14,04

= 42,04 - 14,04

= 28

Answer 4

C1: 72,54 - (30,5 +14,04) = 72,54 -30,5 - 14,04 = (72,54 - 14,04) -30,5 = 58,5 - 30,5 = 28

C2: 72,54 - (30,5 +14,04) = 72,54 - 44,54 = 28

k đúng cho mình nha

Answer 5

Cách 1: 72,54 - ( 30,5 + 14,04 )= 28

Cách 2: 72,54 - 30,5 - 14,04

          = 42,04 - 14,04

          = 28
