Question

1.09×26×0.15可以简算吗？

Answer 1

这道题的简算应该是先算26×0点一五，再乘1.09，这样应该能简单一些

Answer 2

原式可以变化为：
1.09*26*(0.1+0.05)
=1.09*(2.6+1.3)
=1.09*3.9
=1.09*(4-0.1)
=1.09*4-1.09*0.1
=4.36-0.109
=4.251

Answer 3

1.09×26×0.15
＝1.09x（20+6）x0.15
＝1.09x（3+0.9）
＝3.27+0.981
＝4.251

Answer 4

1.09 ×26×0.15
=1.09×13×2×0.15
=1.09×13×0.3
=1.09×3.9
=1.09×(4-0.1)
=1.09×4-1.09×0.1
=4.36-0.109
=4.251

Answer 5

最佳答案：1.09*26*0.15，=1.09*3.9，=(1+0.09)(4-0.1)，=4+0.36-0.1-0.009，=4.251。
