2,15 nhân 23,06 cộng 2,15 nhân 76,94 cộng 17,85

Answer 1

  2,15 x 23,06 + 2,15 x 76,94 + 17,85

=2,15 x ( 23,06 + 76,94 ) + 17,85

=2,15 x 100 + 17,85

=215 + 17,85

=232,85

Answer 2

2.15 * 23.06 + 2.15 * 76.94 + 17.85

2.15 *[23.06+76.94+17.85]

2.15 *117.85

253.3775

Answer 3

2,15 x 23,06 + 2,15 x 76,94 + 17,85 

= 2,15 x ( 23,06 + 76,94 ) + 17,85 

= 2,15 x 100 + 17,85

= 215 + 17,85

= 232,85

Answer 4

2,15x23,06+2,15x76,94+17,85

=2,15x(23,06+76,94)+17,8

=2,15x100+17,85

=215+17,85

=232,85

tck mình nha

Answer 5

       2,15 x 23,06 + 2,15 x 76,94 + 17,85

= 2,15 x ( 23,06 + 76,94 ) + 17,85

= 2,15 x 100 +17,85

= 215 + 17,85

= 232,85

Answer 6

=2,15*( 23,06+76,94 ) + 17,85

=2,15*117,85

=253,3775

chuc ban hoc gioi

Answer 8

 2.15*23.06+2.15*76.94+17.85

=2.15+(23.06+76.94)+17.85

=2.15*100+17.85

=215+17.85

=232.85

Answer 9

2,15 x 23,06 +2,15 x 76,94 + 17,85
