脱式计算。（能简算的要简算）
2.87×（6.3-2.3） 36.5×999+36.5 0.6×（5.3-1.7）÷0.9

Answer 1

2.87×(6.3-2.3)
=2.87×4=11.48
36.5×999+36.5
=36.5×1000=36500
0.6×(5.3-1.7)÷0.9
=6/10×36/10×10/9
=12/5=2.4

Answer 2

2.87×（6.3-2.3）=2.87×4=11.48

36.5×999+36.5 =3.65×(999+1)=3.65×1000=3650

0.6×（5.3-1.7）÷0.9=0.6×3.6÷0.9=2.16÷0.9=2.4

Answer 3

1、原式
=2.87×4
=11.48
2、原式
=36.5x(999+1)
=36.5×1000
=36500
3、原式
=0.6x3.6÷0.9
=0.6×4
=2.4

Answer 4

=2.87X4=11.48，=36.5X(999十1)=3650

追答

=0.6X(3.6/0.9)=0.6X4=2.4
