(4)0.24×5÷5×100(5)1.25×0.5×400(6)0.6×(5.6-4.6)-0.12
答案

(1)原式=0.4×0.25×580

                =0.1×580

                =58(2)原式=7.3×(4.61+5.39)

                =7.3×10

                =73(3)原式=39.6-9.6-14.75

                =30-14.75

                =15.25

(4)原式=0.24×100

                =24(5)原式=1.25×200

                =250(6)原式=0.6-0.12
