(1)10.1-10.1÷1.01(2)4.31×0.99(3)[2× (16-10.6)+3.6]÷0.64 
(4)2.3×4.5-4.5-4.5×0.3 (5)17.46-7.83-2.17 (6)0.25×1.6×2.5
答案

(1)原式=10.1-10

                =0.1

(2)原式=4.31×(1-0.01)

                =4.31-0.0431

                =4.2669(3)原式=[2×5.4+3.6]÷0.64

                =22.5

(4)原式=4.5×(2.3-1-0.3)

                =4.5(5)原式=17.46-(7.83+2.17)

                =7.46

(6)原式=0.25×4×0.4×2.5

                =1
