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

6.8÷0.17x1.6 =40x1.6 =64

0.95 +6.8×0.5 =0.95+3.4 =4.35

0.75x6.8-0.75x5.8 =0.75x(6.8-5.8) =0.75x1 =0.75

看到8和 125就要想到8×125=1000 =14.6×10 =146
