3/4+1/4-3/4-1/4 (5/8+2/27)*8+11/27 36*(7/9+5/6)÷58 2/3*3/5-1/2÷9/4
问题描述：
3/4+1/4-3/4-1/4 (5/8+2/27)*8+11/27 36*(7/9+5/6)÷58 2/3*3/5-1/2÷9/4
答
3/4+1/4-3/4-1/4
=(3/4-3/4)+(1/4-1/4)
=0+0
=0
(5/8+2/27)*8+11/27
=5/8*8+2/27*8+11/27
=5+(16/27+11/27)
=5+1
=6
36*(7/9+5/6)÷58
=(36*7/9+36*5/6)÷58
=(28+30)÷58
=58÷58
=1
2/3*3/5-1/2÷9/4
=2/5-2/9
=18/45-10/45
=8/45
答
3/4+1/4-3/4-1/4 =（3/4-3/4）+（1/4-1/4）=0+0=0(5/8+2/27)*8+11/27 =5+16/27+11/27=5+1=636*(7/9+5/6)÷58 =（36x7/9+36x5/6）÷58=（28+30）÷58=12/3*3/5-1/2÷9/4=2/5-2/9=8/45手机提问的朋友在客户端右上角评...
