(1)21.8-7.22-2.78
=21.8-(7.22+2.78)
=21.8-10
=11.8
(2)9-0.24÷1.6×1.1
=9-0.15×1.1
=9-0.165
=8.835
(3)9.12+9.12×9-6.02
=9.12×(1+9)-6.02
=9.12×10-6.02
=91.2-6.02
=85.18
(4)45.2×66.7+66.7×53.8+66.7
=(45.2+53.8+1)×66.7
=100×66.7
=6670
(5)0.25×0.8×0.125×0.4
=(0.25×0.4)×(0.8×0.125)
=0.1×0.1
=0.01
(6)12.75÷[14.6-(1.3+8.2)]
=12.75÷[14.6-9.5]
=12.75÷5.1
=2.5
=21.8-(7.22+2.78)
=21.8-10
=11.8
