16.08×0.125怎样简便运算
16.08×0.125
=（16+0.08）*0.125
=16*0.125+0.08*0.125
=2*8*0.125+0.08*0.125
=2+0.01
=2.01
再问： 4.27÷28.6×3.59÷42.7×2.86÷35.9=？
再答： 4.27÷28.6×3.59÷42.7×2.86÷35.9 =4.27÷42.7÷28.6×2.86×3.59÷35.9 =0.1÷0.1×0.1 =0.1
再问： 1.1÷【1.1÷1.2】÷【1.2÷1.3】÷【1.3÷1.4】=？
再答： 1.1÷【1.1÷1.2】÷【1.2÷1.3】÷【1.3÷1.4】 =1.1÷1.1×1.2÷1.2×1.3÷1.3×1.4 =1*1.4 =1.4
=（16+0.08）*0.125
=16*0.125+0.08*0.125
=2*8*0.125+0.08*0.125
=2+0.01
=2.01
再问： 4.27÷28.6×3.59÷42.7×2.86÷35.9=？
再答： 4.27÷28.6×3.59÷42.7×2.86÷35.9 =4.27÷42.7÷28.6×2.86×3.59÷35.9 =0.1÷0.1×0.1 =0.1
再问： 1.1÷【1.1÷1.2】÷【1.2÷1.3】÷【1.3÷1.4】=？
再答： 1.1÷【1.1÷1.2】÷【1.2÷1.3】÷【1.3÷1.4】 =1.1÷1.1×1.2÷1.2×1.3÷1.3×1.4 =1*1.4 =1.4
