Question

3.75×0.5−2.75÷2简便？

Answer 1

3.75÷0.5-2.75÷2
=3.75÷2-2.75÷2
=(3.75-2.75)÷2
=1÷2
=0.5
所以可以通过上面的简便计算得到答案是0.5。

Answer 2

3.75×0.5-2.75÷2
解题思路：四则运算规则（按顺序计算、先算乘除后算加减，有括号先算括号，有乘方先算乘方）即脱式运算（递等式计算）需在该原则前提下进行
解题过程：

3.75×0.5-2.75÷2

=（3.75-2.75）×0.5

=1×0.5

=0.5

Answer 3

3.75×0.5−2.75÷2
=3.75×0.5−2.75x0.5
=0.5x（3.75-2.75）
=0.5x1
=0.5

Answer 4

将0.5改为1/2，除以2等于乘以1/2
3.75*0.5-2.75^2
=3.75*1/2-2.75*1/2
=（3.75-2.75）*0.5
=1*0.5
=0.5
答：本题答案是： 0.5

Answer 5

3.75x0.5－2.75÷2
=3.75x0.5－2.75x0.5
=（3.75－2.75）x0.5
=1ⅹ0.5
=0.5
