Укротите дроби. 54/72. 56/68. 56/49. 50/75. 49/98. 17/51

Решите задачу:

$\frac{54}{72} = \frac{3*18}{4*18} = \frac{3}{4} \\\\ \frac{56}{68} = \frac{14*4}{17*4} = \frac{14}{17} \\\\ \frac{56}{49} = \frac{8*7}{7*7} = \frac{8}{7} \\\\ \frac{50}{75} = \frac{2*25}{3*25} = \frac{2}{3} \\\\ \frac{49}{98} = \frac{1*49}{2*49} = \frac{1}{2} \\\\ \frac{17}{51} = \frac{1*17}{3*17} = \frac{1}{3}$
