\(=\dfrac{15}{17}\left(\dfrac{45}{33}-\dfrac{12}{33}\right)=\dfrac{15}{17}\)
= 15/17 x (45/33 - 12/33)
= 15/17 x 33/33
= 15/17 x 1
= 15/17
15/17 x 45/33 - 15/17 x1 2/33
\(=\dfrac{15}{17}\times\left(\dfrac{45}{33}-\dfrac{12}{33}\right)=\dfrac{15}{17}\times\dfrac{33}{33}=\dfrac{15}{17}\times1=\dfrac{15}{17}\)
