Question

34,03x28,54+34,03x71,46+27,05

tính bằng cách hợp lý

Answer 1

34,03 x 28,64 + 34,03 x 71,46 + 27,05

= 34,03 x (28,64+71,46) + 27,05

= 34,03 x 100 + 27,05

= 3403 + 27,05

= 3430,05

Answer 2

34,03 . 28,54 + 34,03 . 71,46 + 27,05

= 34,03( 28,54 + 71,46 ) + 27,05

= 34,03 . 100 + 27,05

= 3403 + 27,05

= 3430,05

Answer 3

34,03.28,54+34,03.71,46+27,05

=34,03.(28,54+71,46)+27,05

=34,03.100+27,05

=3403+27,05

=3430,05

Answer 4

34,03 x 28,54 + 34,03 x 71,46 + 27,05

= 34,03 x ( 28,54 + 71,46 ) + 27,05

= 34,03 x 100 + 27,05

= 3403 + 27,05

= 3430,05

Answer 5

34,03 x 28,54 + 34,03 x 71,46 + 27,05

= 34,03 x ( 28,54 + 71,46 ) + 27,05

= 34,03 x 100 + 27,05

= 3403 + 27,05

= 3430,05
