九分之5+小括号3/4%2分之一小括号等于多少脱式计算

解:5/9+(3/4-1/2) =5/9+1/4 =20/36+9/36 =29/36

36×括号5/18+9分之二括号除以2% =(36×5/18+36×9分之2)×50 =(10+8)×50 =18×50 =900

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

9/5-括号9/5-8/3括号脱式计算 =9/5-9/5+8/3 =0+8/3 =8/3

5/9-(5/6-7/12) =20/36-(30/36-21/36) =20/36-9/36 =11/36

1/2-(5/6-3/8) =1/2-(20/24-9/24) =1/2-11/24 =12/24-11/24 =1/24

六分之5-调括号六分之5减八分之五反括号等于多少脱式计算 (5/6)-(5/6-5/8) =(5/6)-(5/6)+(5/8) =5/8.

8/9-(5/6-1/3) =8/9+1/3-5/6 =11/9-5/6 =22/18-15/18 =7/18

0.125÷12.5%x(2/3+0.5) =0.125x100/12.5x(2/3+0.5) =1x(2/3+0.5) =2/3+1/2 =4/6+3/6 =7/6

1/2-(5/6-3/8) =1/2-(20/24-9/24) =1/2-11/24 =12/24-11/24 =1/24
