Question

[nguyễn kim như anh]

1/2-(1/3+1/4)<x<1/48-(1/16-1/6)

Answer 1

[Vũ Minh Tuấn]

Ta có:

\(\frac{1}{2}-\left(\frac{1}{3}+\frac{1}{4}\right)\)

\(=\frac{1}{2}-\frac{7}{12}\)

\(=-\frac{1}{12}.\)

\(\frac{1}{48}-\left(\frac{1}{16}-\frac{1}{6}\right)\)

\(=\frac{1}{48}+\frac{5}{48}\)

\(=\frac{1}{8}.\)

=> \(-\frac{1}{12}< x< \frac{1}{8}\)

=> \(x=0.\)

Vậy \(x=0.\)

Chúc bạn học tốt!

Answer 2

[Đào Thị Phượng]

1/2 - ( 4/12 + 3/12 ) < x < 1/48 - ( 6/96 - 16/96 )

1/2 - 7/12 < x < 1/48 + 5/48

-1/12 < x < 1/8

Vì -1/12 < 0

1/8 > 0

nên x = 0

Vậy x = 0
