Question

2.84×9.6+0.96×91.6,怎样简便计算?

Answer 1

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

Answer 2

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
=115.2

Answer 3

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

Answer 4

原式=9.6*(2.84+9.16)
=9.6*12
=10*12-0.4*12
=120-4.8
=115.2

Answer 5

第一步把乘式进行化简变换，第二步应用乘法结合律，下一步再进行适当的变形，这样就可以简便运算。现把解题过程拍成图片如下图所示
