求小数加减乘除法,或分数加减法,算式越多越好,必须要有得数,

Answer 1

17×40＝680 , 100－63＝37 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 , 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
