2.8×4+7.2÷0.36 解:=2.8×4+7.2÷(0.09×4) =11.2+7.2÷0.09÷4 =11.2+80÷4 =11.2+20 =31.2

①2.07÷2.5÷0.4,=2.07÷(2.5×0.4),=2.07÷1,=2.07;②21.36÷0.8-12.9,=26.7-12.9,=13.8;③0.125×32×2.5,=0.125×8×4×2.5,=(0.125×8)×(4×2.5),=1×10,=10;④0.65×201,=0.65×(200+1),=0.65×200+0.65×1,=130+0.65,=130.65;⑤1.2×2.5...

=0.36-7.4+0.3-0.6+0.64 =-6.7

(1)2.5×3.7×0.4=(2.5×0.4)×3.7=1×3.7=3.7;(2)13.7×3-36 =41.1-36=5.1;(3)3.07×99+3.07=3.07×(99+1)=3.07×100=307;(4)3.6×13+0.8=46.8+0.8=47.6;(5)0.37×101 =0.37×(100+1)=0.37×100+0.37=37+0.37=37.37;(6)0.125×0.25×0....

38-19=19, 0.36÷0.3=1.2, 2.5×4=10, 3÷7+3÷7= 6 7 8.4÷0.14=60, 2.9×1000=2900, 0.1 3 =0.001, 1 6 - 1 7 = 1 42 , 8 9 ÷ 2 3 = 4 3 , 1÷ 3 5 × 5 3 = 25 9 . 故答案为:19;1.2;10; 6 7 ;60;2900;0.001; 1 42 ; 4 3 ; 25 9 .

解:0.75÷0.25=3 0.125×8=1 4.8÷0.3=16 0.86÷2=0.43 0.56÷28=0.02 0.36÷0.4=0.9 0.64÷0.8=0.8 0.7×9=6.3 3.6÷24=0.15 0.8×1.1=0.88 7.2+12.8=20 46.7-3.8=42.9 12.8÷4=3.2 5.2÷13=0.4 12.5÷5=2.5 1.64+4.1=5.74 10÷20=0.5 24÷15=1.6 8.65×10=86...

直接写出结果. 70-34=36 0×26=0 19+24=43 2.5×0.4=1 84÷7=12 1÷10%=10 0.36+0.4=0.76 0.25÷0.01=25 13+16=12 813+213=1013 1÷16=6 35×23=25
