\(17.\left(\dfrac{5}{17}-\dfrac{1}{34}+\dfrac{1}{2}\right)\)
\(=17.\left(\dfrac{10}{34}-\dfrac{1}{35}+\dfrac{1}{2}\right)\)
\(=17.\left(\dfrac{9}{34}+\dfrac{1}{2}\right)\)
\(=17.\left(\dfrac{9}{34}+\dfrac{17}{34}\right)\)
\(=17.\dfrac{13}{17}\)
\(=13\)
\(17.\left(\dfrac{5}{17}-\dfrac{1}{34}+\dfrac{1}{2}\right)\\ =\dfrac{17.5}{17}-\dfrac{17}{34}+\dfrac{17}{2}\\ =5-\dfrac{1}{2}+\dfrac{17}{2}\\ =\dfrac{9}{2}+\dfrac{17}{2}\\ =\dfrac{26}{2}=13\)
