答案

解:(1)125×9.3×0.08,

=125×0.08×9.3,

=10×9.3,

=93;

(2)13.7×102-2×13.7,

=13.7×(102-2),

=13.7×100,

=1370;

(3)(6.7+6.7+6.7+6.7)×2.5,

=6.7×4×2.5,

=6.7×(4×2.5),

=6.7×10,

=67;

(4)4.5÷[(27.8-25.3)×0.4],

=4.5÷[2.5×0.4],

=4.5÷1,

=4.5;

(5)0.096÷0.01+(75-28÷112),

=0.096÷0.01+(75﹣0.25),

=0.096?0.01+74.75,

=9.6+74.75,

=84.35;

(6)90.8-(7.03-2.17)×4.5,
