Question

2.6×1.42+14.2×0.75-14.2×0.01简便方法？

Answer 1

简便方法计算过程如下：
2.6*1.42+14.2*0.75-14.2*0.01
=2.6*1.42+1.42*7.5-1.42*0.1
=(2.6+7.5-0.1)*1.42
=10*1.42
=14.2
以前就是简便方法计算的过程。

Answer 2

解，原式=2.6x(14.2x0.1)-14.2x0.75-14.2ⅹ0.01
=14.2x(0.26+0.75-0.01)
=14.2x1
=14.2

Answer 3

=（2.6+0.75-0.01）×1.42
=3.4×1.42
=4.828

Answer 4

2.6×1.42+14.2×0.75-14.2×0.01
=2.6×1.42+1.42×7.5-1.42×0.1
=(2.6+7.5-0.1)×1.42
=10×1.42
=14.2
