6/7+1/4-1/6脱式计算

看图

7/9-(1/6+4/9) =7/9-4/9-1/6 =3/7-1/6 =(18一7)/42 =11/42

1/4+1/6-1/8 =6/24+4/24-3/24 =7/24

1/6+1/3+1/2 =1/6+2/6+3/6 =1 8/15+(7/30-1/5) =16/30+7/30-6/30 =17/30 6/7-(1/7+1/2) =6/7-1/7-1/2 =12/14-2/14-7/14 =2/14 9/10-(1/4-1/6) =9/10-1/4+1/6 =54/60-15/60+10/60 =49/60

24×(1/4+5/6-7/8) =6+20-21 =5

1/6+1/5+1/2 =5/30+6/30+15/30 =11/30+15/30 =13/15

7/16*5/6+7/16*1/6-7/16 =7/16*(5/6+1/6-1) =7/16*0 =0

1又1/6x360 ÷7 =7/6÷7x360 =1/6x360 =60
