Detailed step-by-step solution:
The new length of the stick is \(\dfrac{57}{66}~\text{ m}\)
The old length of the stick was \(\dfrac{3}{11}~\text{ m}\) shorter.
Old length of the stick = New length − \(\dfrac{3}{11}~\text{ m}\)
\( = \dfrac{57}{66}-\dfrac{3}{11}\)
\( = \dfrac{57}{66}-\dfrac{3 \times 6}{11 \times 6}\)
\( = \dfrac{57}{66}-\dfrac{18}{66} = \dfrac{57-18}{66} \)
Old length of the stick = \( \dfrac{13}{22}\)
Option A
Given fraction \(=\dfrac{54}{66} \)
Old length of the stick \(= \dfrac{13}{22} = \dfrac{13 \times 3}{22 \times 3} = \dfrac{39}{66} \)
\(54 > 39 \)
So, the given fraction is greater than the old length of the stick.
Option B
Given fraction \(= \dfrac{ 9}{22}\)
Old length of the stick \(= \dfrac{13}{22}\)
\(13 > 9\)
So, the given fraction is not greater than the old length of the stick.
Option C
Given fraction = \( \dfrac{13}{66}\)
Old length of the stick \( = \dfrac{13}{22} =\dfrac{ 13 \times 3}{ 22 \times 3} = \dfrac{39}{66}\)
\(39 > 13\)
So, the given fraction is not greater than the old length of the stick.
Option D
Given fraction \(= \dfrac{11}{22}\)
Old length of the stick \(= \dfrac{13}{22}\)
\(13 > 11\)
So, the given fraction is not greater than the old length of the stick.
Hence, Option A is correct.
