50×0.98简便计算

50×0.98 =50×(1-0.02) =50×1-50×0.02 =50-1 =49 谢谢,请采纳

98*0.51 =(100-2)*0.51 =51-1.02 =49.98

13.5×0.98 解:简便易算 =13.5x(1-0.02) =13.5x1-13.5x0.02 =13.5-0.27 =13.23 祝学习进步。

解: 25-25×0.98 =25×(1-0.98) =25×0.02 =0.5

4.5*0.98+9.8*0.55 =4.5*0.98+55*0.98 =(4.5+55)*0.98 =58.31

原式等于 7.5×(1-0.02) =7.5-0.15 =7.35 所以原式的结果为7.35

0.25×0.98×40 =0.25×40×0.98 =10×0.98 =9.8

76×0.98 =76×(1-0.02) =76×1-76×0.02 =76-1.52 =74.48 结果是74.48

详细步骤写在纸上了
