(1)9.1-1.2÷6-6.24,
=9.1-0.2-6.24,
=8.9-6.24,
=2.66;
(2)4.7×10.2,
=4.7×(10+0.2),
=4.7×10+4.7×2,
=47+9.4,
=56.4;
(3)0.88×4.9+0.88×5.1,
=0.88×(4.9+5.1),
=0.88×10,
=8.8;
(4)2.5×8×0.4×0.125,
=(2.5×0.4)×(8×0.125),
=1×1,
=1;
(5)(5.63-1.88)×2,
=3.75×2,
=7.5;
(6)0.25×43.7×4,
=0.25×4×43.7,
=1×43.7,
=43.7.
=9.1-0.2-6.24,
=8.9-6.24,
=2.66;
