Question

3.7×2.5-3.7÷4的简便算法是什么？

Answer 1

你好，这道题的简便运算，你可以运用乘法分配律来计算哦！计算如下：

3.7×2.5-3.7÷4

=3.7×2.5-3.7×0.25

=3.7×(2.5-0.25)

=3.7×2.25

=8.325。

Answer 2

除法变乘法，再用结合率，小数化为分数

Answer 3

3.7×2.5-3.7÷4=3.7×10/4-3.7×1/4
=37/4-3.7/4
=（37-3.7）/4
=33.3/4

Answer 4

乘法分配律
3.7×2.5-3.7÷4
=3.7×2.5-3.7×0.25
=3.7×(2.5-0.25)
=3.7×2.25

Answer 5

3.7×2.5-3.7×0.25
=(4-0.3)×2.5-(4-0.3)×0.25
=10-0.75-(1-0.075)
=9.25-0.925
=8.325
