一、直接写出结果。
0.8+0.6= 1.25×80= 5.24+3.76= 625×0.8= 4.2-3.6= 0.32÷16=13+0.26=
9.6÷16= 14.5-0.24= 4÷8= 1.3+8.46= 0.8-0.45= 5×2.4= 1-0.01= 8.1÷3=
2.4÷12= 250×0.4= 20.5+2.05= 37.5×400= 0.78+2.2= 1.5×8= 6×1.5=

二、列竖式计算
1.64+2.35= 8.65-6.31= 28.448÷14= 0.58×250= 12.5+3.6=
10.88÷34= 10-7.64= 1.86×7= 13.88-6.29= 926×0.15=
8÷500= 26.3+7.93= 23×7.06= 100.2-2.28= 44÷9(精确到百分位)
