Question

0.29x3.71+2.9x0.629怎么简便计算？

Answer 1

原式=0.29*10*3.71÷10+2.9*0.629
=2.9*0.371+2.9*0.629
=2.9*（0.371+0.629）
=2.9*1
=2.9

Answer 2

0.29×3.71+2.9×0.629的简便计算：
0.29×3.71+0.29×6.29
=0.29×（3.71+6.29）
=0.29×10
=2.9

Answer 3

因为0.29×3.71=2.9×0.371，所以原式等于2.9×0.371+2.9×0.629=2.9×（0.371+0.629）=2.9×1=2.9

Answer 4

0.29×3.71+2.9×0.629 变形得0.29×3.71+0.29×6.29 =0.29×（3.71+6.29） =0.29×10 =2.9

Answer 5

0.29*3.71-2.9*0.629=2.9*（0.371+0.629）=2.9*1=2.9
