1.2÷0.75+0.8的脱式计算

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.

(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)...

(8+0.8)×0.125 =8*0.125+0.8*0.125 =1-0.1 =0.9

0.35*7.8+0.75*7.8_0.78 =0.35×7.8+0.75×7.8-7.8×0.1 =7.8×(0.35+0.75-0.1) =7.8×1 =7.8 不懂请追问

脱式计算 6.8X0.75÷0.5 =5.1÷0.5 =10.2
