黄加纳回答:
(1)9.6×0.8×0.54
=7.68×0.54,
=4.1472;
(2)0.24÷1.2÷0.05
=0.2÷0.05,
=4;
(3)0.72÷0.9×3.5
=0.8×3.5,
=2.8;
(4)1.4×4.2+0.8÷0.5
=5.88+1.6,
=7.48;
(5)9.74÷[(5-3.2)÷3.6]
=9.74÷[1.8÷3.6],
=9.74÷0.5,
=19.48;
(6)4.8÷[(5.6-3.7)÷7.6]
=4.8÷[1.9÷7.6],
=4.8÷0.25,
=19.2;
(7)9.6÷(2.4+1.6×0.5)
=9.6÷(2.4+0.8),
=9.6÷3.2,
=3.
