/是除號
這個是帶答案的
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
可能有點簡單,你看看吧
