Question

[kim dong]

1/3-1/2+a/b=1/2

Answer 1

[Bạch Dương]

\(\frac{1}{3}-\frac{1}{2}+\frac{a}{b}=\frac{1}{2}\)

\(\frac{2}{6}-\frac{3}{6}+\frac{a}{b}=\frac{3}{6}\)

\(\frac{-1}{6}+\frac{a}{b}=\frac{3}{6}\)

                \(\frac{a}{b}=\frac{3}{6}-\frac{-1}{6}\)

                 \(\frac{a}{b}=\frac{4}{6}=\frac{2}{3}\)
