(1)0.63×9.3+0.37×9.3
=(0.63+0.37)×9.3
=1×9.3
=9.3;
(2)25×1.25×3.2
=25×1.25×8×0.4
=25×0.4×1.25×8
=(25×0.4)×(1.25×8)
=10×10
=100;
(3)12.53-1.35×2-9.3
=12.53-2.7-9.3
=12.53-(2.7+9.3)
=12.53-12
=0.53;
(4)2×1.4+2×1.6
=2×(1.4+1.6)
=2×3
=6.
=(0.63+0.37)×9.3
=1×9.3
=9.3;
(2)25×1.25×3.2
=25×1.25×8×0.4
=25×0.4×1.25×8
=(25×0.4)×(1.25×8)
=10×10
=100;
(3)12.53-1.35×2-9.3
=12.53-2.7-9.3
=12.53-(2.7+9.3)
=12.53-12
=0.53;
(4)2×1.4+2×1.6
=2×(1.4+1.6)
=2×3
=6.
