17.5÷1.25÷0.08脱式计算 =17.5÷(1.25x0.08) =17.5÷0.1 =175

=6.89÷(1.25X0.08) =6.89÷0.1 =68.9 望采纳

(1)17.4÷0.8÷1.25,=17.4÷(0.8×1.25),=17.4÷1,=17.4;(2)1.8÷0.2÷0.3,=1.8÷(0.2×0.3),=1.8÷0.06,=30;(3)24÷O.6+0.6÷24,=40+0.025,=40.025;(4)17.94÷3.9+5.3×0.4,=4.6+0.12,=4.72.

5.44÷(1.25×0.8)=5.44÷1 0.4÷0.4×5×5=25 第二个没有简便方法

0.91÷0.8+1.25×1.08 =0.91×1.25+1.25×1.08 =(0.91+1.08)×1.25 =1.99×1.25 =2.4875

(80十0.5)÷1.25和2.4×0.7÷2.4×0.7用脱式计算 解: (80十0.5)÷1.25 =80.5÷1.25 =64.4 2.4×0.7÷2.4×0.7 =2.4÷2.4×0.7×0.7 =1×0.7×0.7 =0.49

脱式: 20÷1.25 =20÷(5/4) =20÷5×4 =4×4 =16

7.86÷8÷1.25 =7.86÷(8*1.25) =7.86÷10 =0.786 【】125*8=1000,1.25*8=10
