括号3/4%3/16反括号乘以括号2/9+1/3反括号

(3/4-3/16)×(2/9+1/3) =9/16×5/9 =5/16

3/8x(-1)又2/5x括号-2又2/3x1又9/16x括号-4又4/7 解:原式=3/8x(-7/5)x(-8/3x15/16)x(-32/7) =6

(3/4-3/16)×(2/9+1/3) =9/16×5/9 =5/16

解: 3/4-3/16*(2/9+1/3) =3/4-3/16 *(2+3)/9 =3/4-3/16*5/9 =3/4-5/48 =(36-5)/48 =31/48

(8/9 + 4/27)x27 =8x3+4 =28

(3/4)X(1/2)-(3/16)÷(9/4) =3/8-(3/16)X(4/9) =3/8-1/12 =9/24-2/24 =7/24

(3/4-3/16)×(2/9+1/3) =(12/16-3/16)x(2/9+3/9) =9/16x5/9 =5/16

(3/4一3/16)x(2/9+1/3) =(12/16一3/16)x(2/9+3/9) =9/16×5/9 =5/16

16分之5
