12/6 x 15/34 x 17/45 = 1/3
11/6 x 12/22 x 13/39 = 1/3
\(\dfrac{12}{6}.\dfrac{15}{34}.\dfrac{17}{45}\)
\(=2.\dfrac{15}{34}.\dfrac{17}{45}\)
\(=\dfrac{2.15.17}{34.45}\)
\(=\dfrac{2}{6}=\dfrac{1}{3}\)
\(\dfrac{11}{6}.\dfrac{12}{22}.\dfrac{13}{39}\)
\(=\dfrac{11}{6}.\dfrac{6}{11}.\dfrac{1}{3}\)
\(=\dfrac{11.6}{6.11.3}\)
\(=\dfrac{1}{3}\)
