Question

tính bằng cách thuận tiện nhất:

8,99*89,9-19,5*8,99+8,99*29,6

 

 

Answer 1

8,99*89,9-19,5*8,99+8,99*29,6

=8,99*(89,9-19,5+29,6)

=8,99*100

=899

Answer 2

8,99*89,9-19,5*8,99+8,99*29,6

=(8,99*10)*(89,9/10)-19,5*8,99+8,99*29,6

=89,9*8,99-19,5*8,99+8,99*29,6

=8,99*(89,9-19,5+29,6)

=8,99*100=899

Answer 3

   8,99 x 89,9 - 19,5 x 8,99 + 8,99 x 29,6

= 8,99 x ( 89,9 - 19,5 + 29,6 )

= 8,99 x 100

= 899

Answer 4

8,99 . 89,9 - 19,5 . 8,99 + 8,99 . 29,6

= 8,99 ( 89,9 - 19,5 + 29,6 )

= 8,99 . 100

= 899

Answer 5

\(899\)

Answer 6

8,99 x 89,8 -19,5 x 8,99 + 8,99 x 29,6
= 8,99 x ( 89,9 - 19,5 + 29,6 )
= 8,99 x 100
=899
