Question

15.6×2.6+1.56×74简便方法？

Answer 1

简算：
15.6×2.6+1.56×74
=15.6×2.6+1.56×7.4×10
=15.6×2.6+15.6×7.4
=15.6×（2.6+7.4）
=15.6×10
=156
运用了乘法分配律

Answer 2

15.6*2.6+1.56*74=1.56*26+1.56*74=1.56*(26+74)=1.56*100=156

Answer 3

15.6×2.6+1.56×74
=1.56x26+1.56×74
=1.56(26+74)
=1.56x100
=156

Answer 4

=15.6*(2.6+7.4)
=15.6*10=156
运用乘法分配律来来简便算法

Answer 5

=1.56×26+1.56×74
=1.56×100
=156
