分数脱式计算怎样算？（过程和答案）
分数脱式计算怎样算？（过程和答案）
1、8分之7+（8分之3-4分之1）
=7/8+3/8-1/4
=7/8+1/8+1/4-1/4
=1+0
=1
2、10分之3+15分之14+5分之4
=9/30+28/30+24/30
=(9+28+24)/30
=61/30
3、2分之1-（2分之1-6分之1）
=1/2-1/2+1/6
=0+1/6
=1/6
分数，“成绩”的意思，如考试分数。分数单位，把单位“1”平均分成若干份，表示这样的一份或几份的数叫分数。表示这样的一份的数叫分数单位。

分式计算求过程和答案
1/(a-b)-1/(a+b)+2b/(a²+b²)=(a+b-a+b)/(a+b)(a-b)+2b/(a²+b²)=2b/(a²-b²)+2b/(a²+b²)=2b(a²+b²+a²-b²)/(a²+b²)(a²-b²)=4a²b/(a^4-b^4)

计算过程和答案
假设这三个数是a,b,c。则这五个数是-13，a,b,c,23，每两个数相差值为y。则：
4y=23-(-13)=36
y=9
那么a=-13+9=-4,b=5,c=14
a+b+c=15
或者用数列的知识回答：
其中此数列定是等差数列。那么b=(23-13)/2=5
a+c=-13+23=10
a+b+c=15
所以这个答案就是15
