9.85×99+98.5×0.1=?简便计算9.85×99+98.5×0.1=?简便计算9.85×99+98.5×0.1=?简便计算9.85×99+98.5×0.1=9.85×99+9.85×1=9.

9.85×99+98.5×0.1=?简便计算
9.85×99+98.5×0.1=?简便计算

9.85×99+98.5×0.1=?简便计算
9.85×99+98.5×0.1
=9.85×99+9.85×1
=9.85×(99+1)
=9.85×100
=985

9.85×(99+1)=985

=9.85x(99+1)

9.85×(99+0.1×10)=9.85×100=985

=9.85X(99十1)=9.85X100=985

=9.85*99+9.85*1=9.85(99+1)=98.5

9.85×99变成98.5×9.9

98.5(99+0.1)

9.85x99+9.85x1
9.85x(99+1)
