9.8÷0.36坚式计算.

列式计算为 0.36×8.9=3.204 所以原式的计算结果为3.204

9.36÷(0.9x0.8)的简便算法 =9.36÷0.9÷0.8 =10.4÷0.8 =13

21.36÷0.8-12.9 =26.7-12.9 =13.8 这是一道小数除法的混合运算

0.36÷9=0.040.01+0.99=11÷0.01=1003.9÷3.9=13.126×100=312.63a+2a=5a1.25×8=104.2÷1.4=310-4.8=5.27.62-1.6=6.020.6×0.4=0.244m-m=3m

21.36÷0.8-12.9 =21.36÷4/5-12.9 =21.36×5/4-12.9 =5·34×5-12.9 =26·7-12.9 =13·8

21.36÷0.8-12.9 =213.6÷8-12.9 =26.7-13+0.1 =13.8

21.36÷0.8-12.9 =26.7-12.9 =13.8

原式 =9/25×5/8+9/25×3/8 =9/25(5/8+3/8) =9/25 满意采纳奥
