(x+ 1/3- 1/4 ) : ( 2 +1/6 - 1/4) = 7 / 46

Answer 1

[Nguyễn Đình Dũng]

( x + 1/3 - 1/4 ) : ( 2 + 1/6 - 1/4 ) = 7/46

( x + 1/3 - 1/4 ) : ( 13/6 - 1/4 ) = 7/46

( x + 1/3 - 1/4 ) : 23/12 = 7/46

x + 1/3 - 1/4 = 7/46 x 23/12

x + 1/3 - 1/4 = 7/24

x + 1/3 = 7/24 + 1/4

x + 1/3 = 13/24

        x = 13/24 - 1/3

        x = 5/24

Answer 2

[Nguyễn Ngọc Quý]

(x + 1/12) : 23/12 = 7/46

(x+1/12) = 7/46 . 23/12

x + 1/12 = 7/24

x = 7/24 - 1/12

x = 5/24
