7又3/4+(-5又4/11)+(-3又1/4)+(-6又5/11)+17又1/4+1又1/4,打错了
可我算出来是11又3/11
追答你错了
追问好吧,我打错了,是(-3又1/4)+(-6又5/11),你帮帮忙,我加悬赏
追答7又3/4+(-5又4/11)+(-3又1/4)+(-6又5/11)+17又1/4+1又1/4
=(7又3/4-3又1/4)+(17又1/4+1又1/4)+(-5又4/11-6又5/11)
=4又1/2+18又1/2-12
=23-12
=11
4+(-11)- (-3\/1)
7又3\/4+(-5又4\/11)+(3又1\/4)+(6又5\/11)+17又1\/4+1又1\/4 =7又3\/4+3又1\/4+17又1\/4+1又1\/4-5又4\/11)+6又5\/11 =30+1又1\/11 =31又1\/11
(+7又3\/4 )+(-5又4\/11)+(-3又1\/4)+(-6又7\/11)+1又1\/4
(+7又3\/4 )+(-5又4\/11)+(-3又1\/4)+(-6又7\/11)+1又1\/4 =(+7又3\/4 )-2-12 = - 6又1\/4
7又3分之2加4又4分之3加-6又3分之1加-9又4分之1
=(7又2\/3-6又1\/3)-(9又1\/4-4又3\/4)=1又1\/3-4又1\/2 =-3又1\/6
7又4分之3加9又5分之4加6又2分之1等于多少?
7又3\/4+9又4\/5+6又1\/2 =31\/4+49\/5+13\/2 =155\/20+196\/20+130\/20 =(155+196+130)\/20 =24.05
计算(+6又3\/5)+(-5又2\/3)+(+4又2\/5)+(+2又1\/7)+(-1)+(-1又1\/7)
(+6又3\/5)+(-5又2\/3)+(+4又2\/5)+(+2又1\/7)+(-1)+(-1又1\/7)=(+6又3\/5) +(+4又2\/5)+(+2又1\/7)+(-1)+(-1又1\/7)+(-5又2\/3)=[(+6又3\/5) +(+4又2\/5)]+[(+2又1\/7)+(-1)+(-1又1\/7)]+(-5又2\/3)=11+0+(-5又2\/3)=5又1\/3 ...
17又3\/4+(-9又11\/5)+(-2.5)+(-17.25)+(-10又11\/6)
17又3\/4+(-9又11\/5)+(-2.5)+(-17.25)+(-10又11\/6)=17又3\/4-9又11\/5-2又2\/4-17又1\/4-10又11\/6 =(17-9-2-17-10)+(3\/4-11\/5-2\/4-1\/4-11\/6)=-21-1 =-22
这是什么问题?
