0.75÷0.25= 16.8÷4= 0.1÷100= 6.3÷0.9=
0.25×8= 0.04×2.5= 1×0.01= 0.1＋0.01=
0.63÷0.9= 0.6＋0.54= 8.9－0.9= 0.96÷2=
5.9－2.5= 4.5×2= 3.6÷3= 0.125×8=
0.53×1000= 72.8×0.01= 1÷125= 1.2÷0.2=
1÷0.01= 48÷0.6= 20÷0.2= 1×0.4=
9.63÷3= 7－0.23= 4.8÷0.3= 7.2－0.8=
1.4×0.5= 29÷100= 6.3÷0.7= 6＋2.4=
12.5×8= 8.9×0= 0.78÷3= 0.35÷0.5=
9.36÷0.9= 100÷0.4= 0.81＋0.09= 0.4×0.9=
10－5.4＝ 4÷20＝ 3.5×200＝ 1.5－0.06＝
0.75÷15＝ 0.4×0.8＝ 4×0.25＝ 0.36＋1.54＝
25 +15 ＝ 47 -27 ＝ 58 +18 ＝ 255 -105 ＝ 1-89 ＝
19 +29 ＝

16 +16 ＝ 23 -13 ＝ 910 +110 ＝ 712 -512 ＝ 12 +15 +12 ＝

8.9－(3+0.9)= 7÷8= 1.5＋2.45= 2×1.7+2×1.3=
0.4×101－0.4= 1.25×0.7×0.8=

0.79+0.79×99＝ 1÷5+1÷5＝ 0.89×101-0.89＝ 2－0.64－0.36﹦
1.1-2.7÷27＝ 12.4×11-12.4= 1.25×3.3×0﹦ 20－3.7－7.3=
5×0.75÷1.5×0.75= 1-0.1×0.1= 6×0.125×8= 1×0.4÷1×0.4=
37.2×99＋37.2= 25×4÷0.25×4= 0.9×7+10.7
9÷5－1.9÷5﹦ 6.8-2.4÷3= 0.6÷0.3+0.5= 1.9+5.1÷51=
1.8÷0.9×0.5= 12-0.05×4= 1×0.01÷0.1= 7.2-1.2+6.7=
25×3.3×0﹦
