Question

3/4 - 1/4 : x = 1/2 ghi cách làm họ mình nhé

Answer 1

\(\frac{3}{4}-\frac{1}{4}\div x=\frac{1}{2}\)

\(\frac{1}{4}\div x=\frac{3}{4}-\frac{1}{2}\)

\(\frac{1}{4}\div x=\frac{1}{4}\)

\(x=\frac{1}{4}\div\frac{1}{4}\)

\(x=1\)

Answer 2

3/4-1/4:x=1/2

1/2:x=1/2

     x= 1/2:1/2

     x=1

Answer 3

3/4-1/4:x=1/2

1/4:x=3/4:1/2

1/4:x=1/4

x=1/4:1/4

x=1

Answer 4

3/4-1/4:x=1/2

  2/4   : x=1/2

            x=2/4:1/2

            x=1

Nếu bạn ko tin thì cứ việc thử lại còn đúng rùi thi tk mk nha ok

Answer 5

\(\frac{3}{4}-\frac{1}{4}:x=\frac{1}{2}\)

=> \(\frac{1}{4}:x=\frac{1}{2}-\frac{3}{4}\)

=> \(\frac{1}{4}:x=\frac{-1}{4}\) 

=> \(x=\frac{1}{4}:\frac{-1}{4}\)

=> \(x=-1\)

Answer 6

\(\frac{3}{4}-\frac{1}{4}\cdot\frac{1}{x}=\frac{1}{2}\)

\(\frac{6}{8x}-\frac{2}{8x}=\frac{4x}{8x}\)

\(\rightarrow4=4x\)

=> \(x=1\)

Ok nha bạn

Answer 7

3/4-1/4:x=1/2

1/4:x=3/4-1/2

1/4:x=1/4

x=1/4-1/4

x=1
