求五年级分数递等式加减法30道!

不能有乘除号!要递等式!

8/9+4/11+1/9= 5/6+3/4-2/3= 11/12-(1/6+1/8)= 11-7/10-3/10= 7/12-(3/4-1/2)=
1/2-(3/4-3/8)= 1/4+2/5-3/10= 5/6-2/3+5/24= 1/2+2/3-2/15= 7/8-(1/2+3/16)=
5/14+3/4+9/14+1/4= 3/10+1/3+1/10= 7/9-(1/6+4/9)= 5/8+1/8-3/10-1/10= 5/9-2/11+4/9=
5/7+1/4=9/14= 5/12+5/18+7/12= 3/8+7/10+5/8= 2-7/9-2/9= 3/10+1/4+2/5=
1-(1/3+3/5)= 2/3+1/6+1/12= 3/4-1/6-1/3= 9/10-1/5-1/2= 4/7+1/6-4/7=
1/4+3/7+1/2= 7/8+1/4+1/2= 我只能帮到这里。
