Question

3.01x6.5的简便计算？

Answer 1

3.01×6.5

=（3+0.01）×6.5

=3×6.5+0.01×6.5

=19.5+0.065

=19.565

Answer 2

这道题可以简便计算，运用四则运算法则，先将3.01分解成3和0.01，再分别乘以6.5后相加求和即可。解题思路如下：3.01*6.5=(3+0.01)*6.5=3*6.5+0.01*6.5=19.5+0.065=19.565 谢谢

Answer 3

这道题可应用乘法分配律简便计算，首先把3.01改写或3+0.01，然后根据乘法分配律用3*6.5，用0.01*6.5，最后再把两个积相加求出结果。3.01*6.5=（3+0.01）*6.5=3*6.5+0.01*6.5=19.5+0.065=19.565谢谢

Answer 4

=（3+0.01）x6.5
=3x6.5+0.01x6.5
=19.5+0.065
=19.565

Answer 5

3.01ⅹ6.5=3ⅹ6.5+0.01X6.5=19.5+0.065=19.565
