三、怎么算简便就怎样算.1/4+3/7+4/7+3/4 2.8/9-1/4+1/2 3.3/8+5/6+5/8 4.2-
4/5+[7/8-4/5] 7/10-[2/15+1/6] 1-1/3-1/7 5/6+11/14 5/6-[4/9-1
（1）1+1/2+1/3+1/4+1/5+1/6+1/7+1/14+1/28
(-3 1/3)+0.5+(-3) 6 1/4+3.3+7+（-3.3）+9-7）+（-3.25）
化简:1/1*2+1/2*3+1/3*4+1/4*5+1/5*6+1/6*7+1/7*8+1/8*9+1/9*10
7/9*5/6/14/27 1/2*2/5+9/10/9/20 5/8*1/4/5/8*1/4 （1/2+2/3+3/4
7/2+9/4+（-1/3)-0.25+（-1/6）
1+2+3+4+5+6+7+8+9+1+11+12+13+14+15````````
1/2+1/3+1/4+1/5+1/6+1/7+1/8+1/9+1/10等于多少?
