先判断哪些式子的商小于l,再用竖式计算1 8.06÷63.01÷7280.8÷120.646÷19.
3.2÷1.6= 5.6÷0.7= 0.54÷0.6=9.9÷0.3= 7.8÷3.9= 2.1÷0.3=0.025÷0.5= 0.72÷0.08= 2.4÷0.4=
口算.5.1÷1.7= 6.3÷0.09= 6.2÷0.1= 0.28÷O.7=2.5÷0.5= 10÷0.5= 10÷0.25= 7.8÷0.6=1÷0.5=
578.6是44的多少倍?
口算.3.6÷1.2= 7.2÷1.2= 2.6÷0.26=0.2×1.5= 0.88÷8= 1.6×3=3.6×0.2= 2.5×2= 5.4÷1.8=
