2.5*1.37*0.4=（2.5*0.4）*1.37=1*1.37=1.37
我会再答：等我一下好吗？再问：嗯再答：
10.75+0.4-9.86=10.75+0.4-(10-0.14)=10.75+0.4-10+0.14=(10.75-10)+(0.4+0.14)=0.75+0.54=1.29
0.4*63*2.5=0.4×2.5×63=1×63=6312.5*8.8=12.5×0.8×11=10×11=110再问：有木有7.6*5.3+7.6*3.7+7.6和12.5*8.8的脱式计算啊再
10.75+0.4+9.86=10.75+0.4+(10-0.14)=10.75+0.4+10-0.14=(10.75+10)+(0.4-0.14)=20.75+0.26=21.01再问：我们不学小数
2.25×0.4+0.6=0.9+0.6=1.5
先算0.4乘0.5
=0.23×）0.4×0.5）=0.23×0.2=0.046
19.61÷（0.4×0.5）再答：�ּ�������0.01
0.5*（6-0.4）=3-0.2=2.8
1.1.84÷(0.25X0.4)=1.84÷0.1=8.42.没简便计算:0.5X(12.76一11.76÷1.2)=0.5X1.483.X÷7=54一54.5X十1=3X9X÷7=495X=26X
2.5Ｘ0.4Ｘ0.9=1Ｘ0.9=0.9
=6.48÷0.6÷(0.5+0.4)=10.8÷0.9=12
=0.25*0.4*13.7=1.37
19.6÷0.4÷0.5=19.6÷(0.4x0.5)=98再答：明白请采纳
4.78x(0.5x0.5x0.4)=4.78x0.1=0.478
=25*0.4*35.86=10*35.86=358.6
36.8×0.4-12.5=37×0.4-(0.2×0.4+12.5)=14.8-12.58=2.22
19.6/（9.8/0.4）=19.6*0.4/9.8=2*0.4=0.86.3/1.8=7*0.9/2*0.9=7/2=3.5
