Question

3.7乘6.5加3.5的简便方法？

Answer 1

这道题的简便计算方法是：3.7*6.5+3.5=3.7（10-3.5）+3.5=37-3.7*3.5+3.5=37-2.7*3.5=37-9.45=27.55。

Answer 2

你好亲，下面是我给你的解答就是

3.7x6.5+3.5
=（3.5+0.2）×6.5+3.5
=3.5×6.5+0.2×6.5+3.5×1
=3.5×7.5+1.3
=（5.5-2）（5.5+2）+1.3
=5.5²-4+1.3
=30.25+1.3-4
=31.55-4
=27.55

Answer 3

3.7×6.5+3.5
=（2.7+1）×6.5+3.5
=2.7×6.5+1×6.5+3.5
=（3-0.3）×6.5+6.5+3.5
=3×6.5-0.3×6.5+（6.5+3.5）
=19.5-1.95+10
=17.55+10
=27.55
