Question

1.25x2.64+12.5×0.726+0.125简便算？

Answer 1

=0.125*10*2.64+0.125*100*0.726+0.125
=0.125*（26.4+72.6+1）
=0.125*100
=12.5

Answer 2

简便计算是直接提取公约数1.25得

1.25x(2.64+7.26+0.1)
=1.25x10
=12.5

注意小数点的变化

0.125x(26.4+72.6+1)
=0.125x100
=12.5

要注意小数点哦

Answer 3

0.125乘26.4+0.125乘72.6+0.125乘1
=（26.4加72.6加1）乘0.125
=100乘0.125
=12.5

Answer 4

都换成1.25嘛，这不就行了：1.25*2.64+1.25*7.26+1.25*0.1
