2.84×9.6+0.96×71.6 =(2.84+7.16)×9.6 =10×9.6 =96

2.84x9.6+0.96x71.6 可以是28.4x0.96+0.96x71.6=（28.4+71.6）x0.96=100x0.96=96 或者2.84x9.6+9.6x7.16=（2.84+7.16）x9.6=10x9.6=96

2.84×9.6+0.96x71.6 =2.84x9.6+9.6x7.16 =9.6x（2.84+7.16）=9.6x10 =96 2.84×9.6+0.96x71.6 =28.4x0.96+0.96x71.6 =0.96x（28.4+71.6）=0.96x100 =96

2.84×9.6+0.96×91.6 =2.84×9.6+9.6×9.16 =(2.84+9.16)×9.6 =12×9.6 =(10+2)×9.6 =10×9.6+2×9.6 =96+19.2 =115.2

2.84*9.6 0.96*71.6的简算：2.84×9.6+0.96×71.6 =2.84×(10×0.96)+0.96×71.6 =2.84×10×0.96+0.96×71.6 =0.96×(2.84×10+71.6)=0.96×(28.4+71.6)=0.96×100 =96 用到了分解法：在某些乘除法算式中，可以把其中的某个数进行分解，使计算简便。例如：...
