`5/8-a/b=1/4+1/6`

`=>5/8-a/b=6/24+4/24`

`=>5/8-a/b=10/24`

`=>5/8-a/b=5/12`

`=>a/b=5/8-5/12`

Answer 2

Answer 3

\(\dfrac{5}{8}-\dfrac{a}{b}=\dfrac{1}{4}+\dfrac{1}{6}\)
\(\dfrac{5}{8}-\dfrac{a}{b}=\dfrac{3}{12}+\dfrac{2}{12}\)
\(\dfrac{5}{8}-\dfrac{a}{b}=\dfrac{5}{12}\)
\(\dfrac{a}{b}=\dfrac{5}{8}-\dfrac{5}{12}\)
\(\dfrac{a}{b}=\dfrac{15}{24}-\dfrac{10}{24}\)
\(\dfrac{a}{b}=\dfrac{5}{24}\)
\(a=5;b=24\)
