Given, improper fraction is \(\dfrac{81}{11}\).
7 ---- Quotient
Divisor ---- 11) 81
77
-----
4 ---- Remainder
\(Mixed \space fraction = \ Quotient \dfrac{ Remainder}{Divisor}\)
\(= 7\dfrac{4}{11}\)
Where, 7 is integral part and \(\dfrac{4}{11}\) is proper fraction.
Hence, \(7 \dfrac{4}{11}\) is the required mixed fraction.
