6.8X0.75/0.5脱式计算

脱式计算 6.8X0.75÷0.5 =5.1÷0.5 =10.2

6.8÷0.5 =68÷5 =13.6

(1)6.8×0.75÷0.5=5.1÷0.5=10.2(2)0.94÷1.25÷0.8=0.94÷(1.25×0.8)=0.94÷1=0.94(3)0.5×4÷0.5×4=(0.5÷0.5)×(4×4)=1×16=16(4)29.4÷7+3.6=4.2+3.6=7.8(5)(7.5-2.3×0.4)÷0.01=(7.5-0.92)÷0.01=6.58÷0.01=658(6)9÷[0.3×(8-6.5)...

6.8×0.75÷0.5,=5.1÷0.5,=10.2,13.75÷0.125-2.75,=110-2.75,=107.25,1.53+23.4÷7.2,=1.53+3.25,=4.78.

0.75÷0.25x6.8 =3×6.8 =20.4

(1)6.8×0.75÷0.5,=68×(0.75÷0.5),=68×1.5,=102;(2)13.5÷2.5-2.75,=5.4-2.75,=2.65;(3)0.125×0.25×32,=0.125×0.25×4×8,=(0.125×8)×(0.25×4),=1×1,=1;(4)0.9+9.9+99.9+0.3,=(1-0.1)+(10-0.1)+(100-0.1)+0.3,=11...

(16.8+7.6)÷.05 =24.4x2 =48.8

看到8和 125就要想到8×125=1000 =14.6×10 =146

0.56X(7.8-5.8)=1.12

4.2/0.6x(7.2-6.8) =7x0.4 =2.8
