森林医生.(下面各竖式算得对吗?对的打“√”,错的打“×”并改正过来)
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=
