异分母分数加减计算题：
1/2+3/10-1/5= 1/2+3/10-1/5= 1-11/20-2/5= 2-6/7+1/7= 5/6+1/7-1/6= 5/6-（1/3+3/10）= 4/9+3/14+9/5= 8/5-5/7-2/7= 9/11-(5/7-2/11) 6/13+3/8+7/13= 9/8-(1/7+1/8)= 8/9+4/11+1/9= 2/7+5/6-1/6= 2/5+1/2-3/4= 7/8-5/12-1/3= 8/9-5/6+2/9= 1/2+3/5-11/20= 2/3+1/6-5/12=
5/8+5/9+4/9= 5/7-5/12+2/7= 9-6/17-11/17= 1-3/8-1/6= 19/10-3/4-1/4= 1/5+7/8+4/5=
5/9-5/12+4/9= 1-2/7-5/7= 1/3+5/9-1/9= 2/3-1/6+1/3= 7/17+6/11-7/17= 2/5+3/10+3/5=
1/3-1/4+3/4= 5/8+8/13+5/13= 2/9+1/4+1/3= 9/10-(3/5+1/6)= 3/4-(1/4-1/5)= 13/20+2/5-7/10=
7/12+3/7+5/12= 3/19-7/15+7/15= 3/5+6/11+2/5= 1+1/5+3/5= 3/4+5/6+1/6= 7/12-5/12-1/12=
1/4+3/8+3/4= 5/6-1/2+2/3= 1/10+508-2/5= 1-2/7+3/8= 3/2-(3/5+3/10)= 8/9+1/4+1/9=
1/9+5/9+4/9= 14/15-2/15+4/15=
解方程:（/是除号,*是乘号)
6x+10=310 46+x=107 231-x=156 x/20=120 x+740=1200
15.8-x=7.68 x-850=440 x/32=14 25x=2900 0.875+x=1.4
x=4x=360 x+56=102 18-x=7.94 47+x=125 x-4.6=5.4
3.5-2x=2.5 3x+1.4=2.6 x+15=20 24.5-x=4.5 0.5x-1.5=1
混合运算
3.07*0.2*10= 8.5*50+2= 0.5*1.3*0.8= 4.8*6+7= 6.4-(4.8-3.6)=
0.26*6*4= 6.54*9*5= 5.9+6.4*5.4= 9.8*7*5= 2.1*4*6=
86*0.4*9= 8-2*3= 0.25+9.6+0.75= 0.2*7*3.4= 25-0.7-0.5=
0.06*9*0.5= 2.3*4+12= 3.01-2+12 2.4*0.6+0.04= 1.24*14*0.8=
我打的有点慢,因为我也是五年级的,我还要写作业,我每天给你打20道解方程和20道混合运算.可以吗?再提高点悬赏嘛~
