脱式计算。（能简算的要简算） (1)(0.2+6.37÷0.7)×0.5 (2)4.7×4.7+4.7+4.3×4.7 (3) 0.125×500×0.2×8 (4) 98.5-14.82÷7.6×3.1

Answer 1

(1)   (0.2+6.37÷0.7)×0.5      =(0.2+9.1)×0.5      =9.3×0.5      =4.65 (2)   4.7×4.7+4.7+4.3×4.7      =4.7×(4.7+4.3+1)      =4.7×10      =47 (3)   0.125×500×0.2×8      =(0.125×8)×(500×0.2)      =1×100      =100 (4)   98.5-14.82÷7.6×3.1      =98.5-6.045      =92.455
