副号1-1/4×8/9括号除以7/9脱式计算

35除9+47除9一7除9一12除9=多少,用脱式计算? 35÷9+47÷9-7÷9-12÷9 =(35+47-7-12)/9 =63/9 =7

1/22/3×括号3/4-1/6括号除以7/9脱式计算解:1/2+2/3×(3/4-1/6)除以7/9=1/2+2/3×7/12÷7/9=1/2+1/2=1

9.8÷7.3×(5.3-2.5) =9.8÷7.3×2.8 =9.8×2.8÷7.3 =27.44÷7.3 =1372/365

(1)8/9×[7/8-(7/16-1/8)](2)10×3/4+17×75%-7×0. =8/9×[7/8-7/16+1/8] =8/9×[7/8+1/8-7/16] =8/9×[1-7/16] =8/9×9/16 =1/2 (2)10×3/4+17×75%-7×0.75 [3/4=75%=0.75] =0.75×(10+17-7) =0.75×20 =15

7/9+5/12-1/4脱式计算 =84/108+45/108-27/108 =102/108 =51/54

(7/8-3/16)x(1-1/9) =(11/16)x(8/9) =11/18.

9分之7-括号5/18+6分之一括号脱式计算 =14/18-5/18-3/18 =9/18-3/18 =6/18 =1/3

(7/9+4/21-3/7)乘6.3 =7/9x6.3+4/21x6.3-3/7x6.3 =4.9+1.2-2.7 =3.4

1. 1/8*14/8/7 =7/4/8/7 =7/4*7/8 =49/*32 2. 9/14/(6/5-3/4)*7/24 =9/14/9/20*7/24 =9/14*20/9*7/24 =20/14*7/24 =5/12 第三小题题目再发准确点行吗

8/9×[3/4-(7/10-25%)脱式计算怎么算? 8/9×[3/4-(7/10-25%) =8/9*(3/4-7/10+1/4) =8/9*(1-7/10) =8/9*3/10 =4/15
