11/24*16 =11*2/3=22/3 1/4*2/7=1/14 6/12*6+5/12*6 =3+5/2=11/2 3/5*5/6 =1/2 5/13*4/7*14=40/13

3/5*5/16*1/3=1/16 ( 1/5+2/3)*15 =3+10=13 5/18*1/4*9/10 =5*9/18*4*10=1/16 7/11*3/8*4/9=7*3*4/11*8*9=7/66

（7/12+7/8 ）*36 =21+63/2=105/2 8/25*5/6+1/6*8/25 =8/25（5/6+1/6）=8/25

1/2-1/2*1/4 =1/2（1-1/4）=1/2*3/4=3/8 137*7÷136=（136*7+7）/136=7+7/136=143/136

2/5*11-2/5=2/5（11-1）=2/5*10=4
