一个正方体的棱长总和是96cm,这个正方体的棱长是多少厘米?
2×5= 4.2﹣1.8= 12.5×8= 3.54×10= 5.2+0.8= 2.15+1.85= 0÷0.25= 2÷0.4= 9÷6= 70×50=
直接写出得数 10﹣0.92= 1﹣0.25= 3.2+7.68= 1÷0.01= 1.3×2.7= 2.08×0.5= 0.66÷0.2= 10.5÷0.03= 2.05÷0.05=
直接写出得数: 0.18+0.32= 180÷3.6= 2÷1+1÷2= 3﹣0.05= 2.6×50= 0.3÷0.1×10= 1÷0.02= 1.25×16= 0.25×3.9×4=
用竖式计算 9﹣8.01= 46+0.54+0.07= 0.25×98.7= 3.572÷0.47=
直接写出计算结果. 1.7×0.5= 4÷0.8= 5.6﹣2.3= 0.125×4= 1.44÷1.2= 3.2÷1= 3.07×100= 1.8×5= 0.36÷3.6= 9.6÷1.2= 0÷0.9= 0.1×0.12= 1.5÷0.3×0.2= 12.5+12.5÷12.5= 0.6+0.6÷0.6﹣0.6= 4.2×0.7+4.2×0.3= (8.5﹣1.5)÷0.1= 20﹣3.7﹣6.3=
