这个是带答案的
2.8×0.4= 1.12
14-7.4=6.6, 1.92÷0.04=48, 0.32×500=160, 0.65+4.35= 5
10-5.4=4.6, 4÷20=0.2, 3.5×200=700, 1.5-0.06=1.44
0.75÷15=0.05, 0.4×0.8=0.32, 4×0.25=1, 0.36+1.54=2
1.01×99=99.99, 420÷35=12, 25×12=300, 135÷0.5=270
3/4 + 1/4 =1, 2 + 4/9 =22/9, 3 - 2/3 =7/3, 3/4 - 1/2= 1/4
1/6 + 1/2 -1/6 =1/2, 7.5-(2.5+3.8)=1.2, 7/8 + 3/8 =5/4
3/10 +1/5 =1/2, 4/5 - 7/10 =1/10, 2 - 1/6 -1/3 =1.5
0.51÷17=0.03, 32.8+19=51.8, 5.2÷1.3=4, 1.6×0.4= 0.64
4.9×0.7=3.43, 1÷5=0.2, 6÷12=0.5, 0.87-0.49=0.38
可能有点简单,你看看吧
