Question

4.7x0.5x2.6怎样简便计算？

Answer 1

4.7×0.5×2.6
=4.7×（0.5×（2+0.6）
=4.7×（0.5×2）×（0.5×0.6）
=4.7×1×0.3
=1.41

Answer 2

4.7×0.5×2.6=6.11
4.7×0.5=2.35
2.35×2.6=6.11
0.5×2.6=1.3
4.7×1.3=6.11

Answer 3

原式=4.7×1.3
=(5-0.3)×(1+0.3)
=5×1+5×0.3-0.3×1-0.3×0.3
=5+1.5-0.3-0.09
=5+1.20-0.09
=5+1.11=6.11希望采纳，谢谢。

Answer 4

4.7×0.5×2.6
=4.7×0.5×2×1.3
=4.7×1×1.3
=4.7×1.3
=4.7×(1+0.3)
=4.7×1+4.7×3÷10
=4.7+1.41
=6.11

Answer 5

=0.5×2.6×4.7
=1.3×4.7
=1.3×（5－0.3）
=1.3×5－1.3×0.3
=6.5－0.39
=6.11
