(1)4.67-(2.98+0.67),=4.67-0.67-2.98,=4-2.98,=1.02;(2)849÷[98-(18+37)],=849÷[98?18?37],=849÷[1-37]=849÷47,=27;(3)8×0.4×12.5×2.5,=(8×12.5)×(0.4×2.5),=100×1,=100;(4)125×(8+0.8+0.08),=125×8+125×0.8+12...

(1)4.67-(2.98+0.67)=4.67-2.98-0.67=4.76-0.76-2.98=4-2.98=1.02(2)73.8×16-73.8×6=73.8×(16-6)=73.8×10=738(3)(45+14)÷73+710=2120×37+710=920+1420=2320

4.67-(2.98+0.67)=4.67-0.67-2.98 =4-3+0.02 =1.02
