0.3+1.5 2.5+9.8 7.6+1.3 4.4+5.7 2.3+7.7 5.7+3.1 7.69+2.31 9.16+2.64 5.68+12.22 16.8+16.5 26.3+14.6+2.1 96.9+3.4+0.7 32.2+2.1 6.4+8.2 28.01+2.09 3.4+6.8 6.9+7.1+3.6-2.4 6.8-3.8 4.26-3.71 8.1+3.6 23.1+23.9 6.94-3.12 3.8+2.4 5.6-4.66+0.6

17*40= 100-63= 3.2+1.68= 2.8*0.4= 14-7.4= 1.92÷0.04= 0.32*500= 65+4.35= 10-5.4= 4÷20= 3.5*200= 1.5-0.06= 0.75÷15= 0.4*0.8= 4*0.25= 36+1.54= 1.01*99= 420÷35= 25*12= 135÷0.5= 0.51÷17= 32.8+19= 5.2÷1.3= 1.6*0.4= 4.9*0.7= 1÷5=

6.84-5.73= 5.2-0.08= 3.25+0.75= 0.97+6.13= 4.9-0.85= 2.13+6.89= 1.72+3.6= 17.20.36= 11.6-9.23= 0.78+2.2= 5.2-0.08= 3.25+0.75= 4.22+8.46= 5.63+1.25= 5.63+1.25= 9.36-1.59= 4.65-1.15= 7.65-4.19= 8.88-2.69= 0.72+0.91= 8.24+3.76= 4.

小数加减法练习题1、口算 2.5+0.9 = 3.6+4.9 = 5.6 4.8 = 31.6= 3.06+ 4.4 = 8.8 +4.5= 5.2 + 4.8 = 32.9=2、计算下面各题并且验算3.64+1.48 22.32 +12.59 7.85 +11、口算 2.5 + 0.9 = 3.6 + 4.9 = 5.6 4.8 = 31.6= 3.06 + 4.4 = 8.8 + 4.5= 5.2 + 4.8

1.2+2.8=41.5+3.6=5.122.5+23=45.50.125+0.348=0.4730.65+2.35=34.27+3.15=7.423.24+1.157+0.163=4.540.12+3.16=3.280.124+3.15=3.27422.26+3.16=25.420.14+10.46=10.61.238+0.152=1.394.12+5.18=9.310.56+12.44=2310.2+0.8+10.58=21.580.23+0.37+12.35=12.95

1.5+3.5=5 5.5-4.6=0.9 7.9X5.6=44.24 89.6除以6.5=13.784615.

1.4+4.5=5.9用跟加减一样的方法.

1.2+96.6= 2.6-35.6= 10.23-0.88= 4.56+14.62= 7.9+53.1= 56.4+23.1= 96.4-57.1= 55.1+65.9= 56.78-21.5= 96.1-43.2=0.9+1= 45÷3= 2.7+3.9= 416÷4= 18*4= 1-0.44= 0.7+0.9= 3.25+0.75= 14.6-0.4= 10-0.1= 1-0.78= 1-0.3= 5-0.08= 1.1-1=1.64+2.35=

1) 500+(407+0)= 2) 386+382+114= 3) 42+(91+158+109)= 4) (87+103+113)+97= 5) (246+387+154)+13= 6) 49+(71+151+129)= 7) 255+(79+45)=
