Question

Answer 1

`7/8 : 12/5 - 5/8 : 12/5 + 9/8 .5/12`

`=7/8 . 5/12 - 5/8 . 5/12 + 9/8 . 5/12`

`=(7/8-5/8 + 9/8) . 5/12`

`= ((7-5+9)/8) . 5/12`

`=11/8 . 5/12`

`=(11.5)/(8.12)`

`=55/96`

Answer 2

\(=\dfrac{7}{8}\cdot\dfrac{5}{12}-\dfrac{5}{8}\cdot\dfrac{5}{12}+\dfrac{9}{8}\cdot\dfrac{5}{12}\)

\(=\dfrac{5}{12}\left(\dfrac{7}{8}-\dfrac{5}{8}+\dfrac{9}{8}\right)=\dfrac{5}{12}\cdot\dfrac{11}{8}=\dfrac{55}{96}\)

Answer 3

f, 55/96
