Answer 1

530-70= 0.37×20= 6.43+1.95= 48÷0.6=
8.5-0.24-1.76= 350÷50= 8.5÷5= 320÷40=
45-32= 1.8×6-1.8= 11) 12.4+0.37= 1-0.62=
720÷9028×6= 25×8×125×4= 0.36÷3= 1-0.76=
8500×4= 69×7= 4.8÷0.6+4.8÷0.4= 1.44÷9=
2.8×0.4＝ 14－7.4＝ 1.92÷0.04＝ 0.32×500＝ 0.65＋4.35＝ 10－5.4＝
4÷20＝ 3.5×200＝ 1.5－0.06＝ 0.75÷15＝ 0.4×0.8＝
4×0.25＝ 0.36＋1.54＝ 1.01×99＝ 420÷35＝ 25×12＝300
135÷0.5＝ 12×40= 6+7.8= 45-32= 1.12×100=
3.9-2.8= 4.83-2.53= 2.4÷0.6= 0.32×0.2×5=
240÷3= 0.04×25= 1.25×0.8= 1.8÷0.9=
9×1.25×8= 1.7×3= 27÷0.01= 25×8×125×4=
5600÷8= 5.2×0= 26×3= 30×(200+3)= 0.8×0.7= 0.25×28=
48÷0.6= 2.73-0.63= 0.81÷0.9= 4.5+0.55=
560+80= 1-0.76= 720÷80= 350÷50=
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＝
1.01×99＝ 420÷35＝ 25×12＝ 135÷0.5＝
3/4 + 1/4 = 2 + 4/9 = 3 - 2/3 = 3/4 - 1/2=
1/6 + 1/2 -1/6 = 7.5-(2.5+3.8)= 7/8 + 3/8 =
3/10 +1/5 = 4/5 - 7/10 = 2 - 1/6 -1/3 = 2.8×0.4＝
0.51÷17＝ 32.8＋19＝ 5.2÷1.3＝ 1.6×0.4＝
4.9×0.7＝ 1÷5＝ 6÷12＝ 0.87－0.49＝
1. 89÷100= 0.82+0.08= 73×1= 0.63×10= 4÷10=
17÷1000= 0.56+0.4= 1.25×100= 5.6+99= 100÷25=
1-0.93= 90-0.9= 248－198= 68×25= 6756－193－207=
72×125= 97×360＋3×360=
