Question

These are some unfinished calculations. Complete them to find each difference

Answer 1

`\begin{gathered} 9(4)/(8)-(7)/(8) \\ =(76)/(8)-(7)/(8) \end{gathered}`
`(76)/(8)-(7)/(8)=(76-7)/(8)=(69)/(8)\text{ or 8}(5)/(8)`

for 2nd question

`\begin{gathered} 9(4)/(8)-5(1)/(8)=(76)/(8)-(41)/(8) \\ =(76-41)/(8)=(35)/(8)\text{ or 4}(3)/(8) \end{gathered}`

for 3rd question,

`\begin{gathered} 9(4)/(8)-3(5)/(8)=(76)/(8)-(29)/(8) \\ =(76-29)/(8)=(47)/(8)\text{ or 5}(7)/(8) \end{gathered}`

for 4th question,

`\begin{gathered} 5(1)/(8)-3(5)/(8)=(41)/(8)-(29)/(8) \\ =(41-29)/(8)=(12)/(8)=(3)/(2)\text{ or 1}(1)/(2) \end{gathered}`
