Question

Tìm x biết 1/2 : 2x = -1/3

 

Answer 1

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

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

\(2x=\frac{3}{2}\)

\(x=0,75\)

Answer 2

2x=1/2:(-1/3)

2x=1/2.(-3)

2x=-3/2

x=-3/2:2

x=-3/2.1/2=-3/4

Vay x=-3/4

Answer 3

\(\frac{1}{2}\div2x=-\frac{1}{3}\)

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

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

\(2x=-\frac{3}{2}\)

\(x=-\frac{3}{2}\div2\)

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

\(x=-\frac{3}{4}\)

Answer 4

1/2 : 2x = -1/3

2x = 1/2:(-1/3)

2x = 1,5

x=1,5:2

x = 0,75

Vậy x=0,75

Answer 5

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

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

\(2x=-\frac{3}{2}\)

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