计算下面各题能简算的要简算 5/6-1/2+1/4 5/12+3/4-5/8 4/5-(3/10+1/6) 5/9+7/18+4/9 1-2/7-5/72/3+5/13+1/3
5/6-1/2+1/4
=5/6-1/4
=10/12-3/12;
=7/12;
5/12+3/4-5/8
=10/24+18/24-15/24
=13/24;
4/5-(3/10+1/6)
=24/30-9/30-5/30
=10/30
=1/3;
5/9+7/18+4/9
=(5/9+4/9)+7/18
=1+7/18
=25/18;
1-2/7-5/7
=1-(2/7+5/7)
=1-1
=0
2/3+5/13+1/3
=1+5/13
=18/13;
