五年级分数脱式计算题，是分数！！！！！！！！！！60道

Answer 1

如下：

1、(125+8)x8

=133x8

=1064

2、（250÷50）+（12×4）

=5+48

=53

脱式计算是一个数学学科术语，即递等式计算，把计算过程完整写出来的运算，也就是脱离竖式的计算。

脱式计算方法：

主要掌握的是记住要先算乘、除法，后算加、减法。在乘除法连继计算时中，要按从左往右的顺序依次计算。遇到括号，要首先计算括号内部。

在脱式过程中要按运算顺序划出运算顺序线，还要做到“三核对”，一要核对从书上把题抄到作业本上数字、符号是否抄对。二要核对从横式抄到草稿竖式的数字、符号是否抄对。三要核对把草稿竖式上的得数，抄到横式上是否抄对，小数点是否点对地方，有无遗漏。

1-(1/2-3/4)
=1+3/4-2/4
=1+1/4
=5/4

1-1/2-1/4
=1/2-1/4
=2/4-1/4
=1/4

2/7-8/9+5/7
=(2/7+5/7)-8/9
=1-8/9
