脱式计算。(能简算的要简算)
(1)16.8-6.8×0.25(2)0.25×6.5×40
(3)0.25×32×1.25(4)7.3×0.64+9.36
(5)10.1×0.99(6)4.66×0.28+4.66×0.82-4.66
答案

(1)原式=16.8-6.8×0.25

                =16.8-1.7

                =15.1(2)原式=0.25×40×6.5

                =10×6.5

                =65

(3)原式=0.25×4×(8×1.25)

                =1×10

                =10(4)原式= 4.672+9.36

                =14.032

  

(5)原式=(10+0.1)×0.99

                =9.9+0.099

                =9.999(6)原式= 4.66×(0.28+0.82-1)

                = 4.66×0.1

                =0.466
