分数四则简便运算题25道。可以出题的帮帮忙吧!O(∩...

1.125*3+125*5+25*3+25 2.9999*3+101*11*(101-92) 3.(23/4-3/4)*(3*6+2) 4. 3/7 * 49/9 - 4/3 5. 8/9 * 15/36 + 1/27 6. 12* 5/6 2/9 *3 7. 8* 5/4 + 1/4 8. 6÷ 3/8 3/8 ÷6 9. 4/7 * 5/9 + 3/7 * 5/9 10. 5/2 -( 3/2 + 4/5 ) 11. 7/8 + ( 1/8 + 1/9 ) 12. 9 * 5/6 + 5/6

(1+2/3)*(1-2/3)*(1+2/5)*(1-2/5)**(1+2/99)*(1-2/99) =(1+2/3)*(1+2/5)**(1+2/99)*(1-2/3)*(1-2/5)**(1-2/99) =5/3*7/5**101/97*1/3*3/5**97/99 =1/3*101*1/99 =101/297

3/4-1/2= 1-1/8= 11/12-1/6= 1/5+1/4= 1/2-1/3=5/6-1/3= 3-5/6= 17*40= 100-63= 3.2+1. 4÷20= 3.5*200= 1.5-0.06= 0.75÷15= 0.4*0.8= 4*0.25= 0.36+1.54= 1.01*99= 420÷35=

1*25+4*25+3*25-4*25=100

1、计算下面各题,能简便计算的用简便方法计算.9分之7÷5分之11+9分之2*11分之5 所以第二天比第一天少修路:120-90=30(米)也可以:120*(1-4分之3)=30(米

1. 3/7 * 49/9 - 4/3 =1 2. 8/9 * 15/36 + 1/27 =11/27 3. 12* 5/6 2/9 *3 =28/3 4. 8* 5/4 + 1/4 =41/4 5. 6÷ 3/8 3/8 ÷6 =255/16 6. 4/7 * 5/9 + 3/7 * 5/9 =5/9 7. 5/2 -( 3/2 + 4/5 ) =1/5 8. 7/8 + ( 1/8 + 1/9 ) =10/9 9. 9 * 5/6 + 5/6 =25/3 10. 3/4 * 8/9 - 1/3 =1/3

45 * 2/3 + 1/3 * 15 27.7/19 + 12/19 * 5/6 28.1/4 + 3/4 ÷ 2/3 29.8/7 * 21/16 + 1/2 30.101 * 1/5 1/5 * 21 3.(23/4-3/4)*(3*6+2) 4.3/7 * 49/9 - 4/3 5.8/9 * 15/36 + 1/27 6.12* 5/6 2/9 *3 7.8* 5/4 + 1/4 8.6÷ 3/8 3/8 ÷6 9.4/7 * 5/9 + 3/7 * 5/9 10.5/2 -( 3/2

(1) 103÷73-159-57= (2) 83*91÷131+38= (3) 197-46+67-13= (4) 38÷54*126-52= (5) 192+52*136÷66= (6) 123-47+159-16= (7) 164*23-126+74= (8) 117+21+17-19= (9) 7÷9*161+93= (10) 93*35-128+36= (11) 86*9*187*99= (12) 68÷83-14÷54= (13

1.8/7 * 21/16 + 1/2 2.101 * 1/5 1/5 * 21 3.(23/4-3/4)*(3*6+2) 4.3/7 * 49/9 - 4/3 5.8/9 * 15/36 + 1/27 6.12* 5/6 2/9 *3 7.8* 5/4 + 1/4 8.6÷ 3/8 3/8 ÷6 9.4/7 * 5/9 + 3/7 * 5/9 10.5/2 -( 3/2 + 4/5 ) 11.7/8 + ( 1/8 + 1/9 ) 12.9 * 5/6 + 5/6 13.3/4 * 8/9 - 1/3
