2/1+5/4-2/1+5/4简便计算？ To simplify the expression 2/1 + 5/4 - 2/1 + 5/4, we need to find a common denominator for all four fractions before adding or subtracting them. The common denominator for 2/1 and 2/1 is 1, since both fractions already have the same denominator. The common denominator for 5/4 and 5/4 is 4, since both fractions already have the same denominator. Therefore, the simplified expression is: 2/1 + 5/4 - 2/1 + 5/4 = (2 + 5)/1 + (5 + 5)/4 = 7/1 + 10/4 = 7 + 10/4 = (7*4 + 10)/4 = (28 + 10)/4 = 38/4 = 19/2也可能是软件上的阻碍，比如商业主体的认知或是管理上的滞后等等”。 从租购房补贴到岗位补贴，从子女教育到医疗服务，肥西县为高层次人才量身定制了一揽子的保障政策，聚焦人才全阶段、全要素发展需求。
